RUUD GAS FURNACE NO HEAT CALL 8 DEGREE DAY

[@greggaieck4808]

Steven lavimonier I like your utube videos are awesome 👍👍👍👍👍😎😎😎👍

[@sacongo1624]

How about this for a shortcut since you stock new gas valves in your truck next time just connect the wires to a new one without mounting it then give it a start if you hear it sparking you know its the gas valve. A little Monday Morning Quarterback Next Level Mama!

[@denrayr]

You're right on, Steve. The control is sensing that there isn't enough load on the valve circuit. It's a poor design, though. They should have the control board issue an error code that gives you the information that the gas valve is out of range. Nice job figuring it out. That one was a real head scratcher.

[@tomhaeussler6553]

I’ve been doing this work for 32 years and I still learn something new every day!

[@RaulRM3]

Glad to hear that makes me not feel so bad sometimes lol

[@RickSegui]

So, he has to pay for a board that isn’t needed?

[@danwright216]

Good find on the problem, the gas valve and ignitor are energized at the same time. The coil drawing high ohms like that causing the board to drop out on the spark circuit. Very interesting video.

[@chuckquinn8026]

I lost my board and thermostat on Thanksgiving…not sure which one took the other out. 4 year old Trane with very expensive Trane communicating thermostat…new board would only fire with thermostat bypassed 🤦🏻‍♂️. Ended up trashing Trane thermostat and went with Ecobee. Excellent unit at 1/3 price of Trane XL1050

[@neutrodyne]

These modern systems can be a pain for sure. My guess is that the control board did not sense a load on it from the gas valve and that made it go to a type of shut down mode.

[@jeffdickens7019]

Hey Stephen you are a very good technician and I think I'm a pretty good technician too but my grandfather did it for 65 years and he said you learn something new everyday

[@muxxor9492]

Unrelated to the issue he was having but I noticed on the new board the first dip switch isn’t set to the ON position like on the original board. I think SW1 is to set Up Flow or Down Flow. It looks like the new board is set properly for Up Flow but the old board was set to Down Flow. I assume this is upflow setup.

[@jeremygoldsworthy]

Happens with all the Ruud units I encounter with a Honeywell gas valve. We put in the WR valves as a replacement and don’t look back.

[@edwardkuntush9339]

Nice catch Steve, every once and a while the real issue eludes you till you go a bit deeper .... nice to see you still keep an open mind on stuff ... when Michelangelo was old and famous people would constantly lavish him with praise and he was known to smile and politely say "I'm still learning"

[@Boilerking76123]

The best part is you might never see that again. The old Fireye E100 controls would do that with a bad gas valve. It would pull the control voltage down below 100 volts , like turning the burner switch off and it would restart the cycle.

[@glennfranklin4523]

Great diagnosing and repair man at that temperature he sure enough needed that heat working

[@WeatherNut27]

[@bobparrott8130]

😃👍 Good Job Steve Sometimes if gas valve shorts out it backfeeds circuit board which toasted the circuit board... not your fault

[@jimmyp5487]

Correct 👍

[@WeatherNut27]

Good one here.. love these real life troubleshooting videos.

[@tyhuffman5447]

I would say that the only thing to consider is what appears to be previous problem bias, that was noted when you said "maybe you got a bird in there" which was a previous problem. This may have wasted time and effort in getting to the heart of the matter. When troubleshooting bias can start to lead you down the prong path and that makes getting back on track all that more difficult. I have watched you sort out the gas valve issues much quicker and probably could have this time. I would say this one just got away from you, but you salvaged a valuable lesson. I just think you are better than that.

[@zacharyreed45]

I could not really tell but, it did sound like the original GV clicked. Almost like when the PCB went to engage coil on GV current was eaten by excessive resistance. Acted like it lost its 24v from transformer then restarted. Basically power cycling itself via 24v everytime it engaged GV coil.

[@jackl9922]

Wow. What a tough one. Great to have an understanding customer. I remember that install video. You’re much nicer than my local GM service center.

[@Fireship1]

Tricky one for sure. I was thinking the board was bad right off as well. Nice find and fix Steve.

[@winkhvac62]

I put in a lot of those unit RUDD I have not run to this problem yet. Good one steven!!👍

[@andrewhepfinger3990]

SO, WAS THERE NO WAY TO SEE THAT THE GAS VALVE WAS THE ISSUE BEFORE REPLACING THE BOARD?

[@kevinharris8926]

Good job working on it

[@search_eternal]

I had a Lennox doing the same thing the other week and it ended up being the gas valve. The ignitor would glow and the gas valve would click and then click right off. Changed the valve and boom as you say "Huston we have ignition".

[@henrykiser8880]

What were the dip switches on the board for? I think the new board was set different.

[@themayorofairconditioning2868]

Another great video. Thanks for posting

[@josephlivoti8143]

Does it matter how you put the wires back on the gas valve?

[@tytig94]

Not on single stage valves

[@jo6520]

Would that be covered under warranty if its that new?

[@jimmyday9536]

Only defective parts would be covered.

[@Damian-ir8gn]

So what’s the normal range should the gas valve have

[@NW_drew]

3.5

[@johnstuart3851]

Resistance of old gas valve was ~82 Meg Ohms, an open circuit. New valve 6.9 Ohms.

[@jeffreykreft5442]

It was not going to send power to the ignition because it thinks the gas valve is already open. It is part of the safety loop. Not very often that these go bad in this way, he must of had a power surge at some point which cause the coil to begin to melt, that's6 why you were getting the high reading. Good catch on that, allot of technicians would have never figured this one out.

[@tedbell4416]

That's what I thought some kind of power surge maybe

[@erikb8815]

I ran into the same problem last winter on a 4 year old rheem. However doesn’t Ruud have 10 year warranty on parts?

[@myrtlebeachbum1373]

yes, if registered within 90 days of install

[@jameschant1135]

So, did the old board go back in or was it bad too?

[@additudeobx]

Gas Valve is just an inductive coil relay valve. It is not going to operate if the coil resistance is 10x times specification. The resistance of the coil will minimize the current thru the coil even at rated voltage 24v and affect the inductive flux density of the coil and the plunger/armature will not operate at the reduced current level caused by excessive resistance. General rule of thumb, that physical size relay, 6-9 ohms, larger physical size ones 10-14 ohms, small physical size ones 1-5 ohms. 10%-15% tolerance.

[@dimaslespier2688]

Good video. But anytime you’re not getting codes on that board. Always know. There is something dragging down the control circuit. Anything from a bad stat to a grounded safety device to a pinched wire or bad valve coil.

[@billkrause4585]

Steven, that was a great FIND, and how you troubleshot the Gas Valve with your meter was a treat for me to see. I enjoy you showing us the 'how to' finding the problem with you multimeter. Yeah, that wasn't just like school, it was class (get it?).

[@derekcattoi3326]

Had the same issue on a rheem ended up being a bad gas valve.

[@strayerhvac1416]

I had the exact same problem on a daikin RTU I changed the board and same problem disconnected the gas valve to check voltage and it started sparking so I went and told the store owner I screwed up and it was the gas valve he got all pissed off so I told him I could have lied to him and said it was both he finally approved the gas valve and unit has ran fine since.

[@nellayema2455]

Do you have to match the dip-switch settings on the new board to the old board?

[@dissociativecat7495]

good info

[@fanofoldfans9238]

Great job on that PITA Steve! I'd like to take that plastic cover off the gas valve and see if it was a bad solder joint or a fried solenoid coil? Safety systems work though...

[@DiverCTH]

Same here. I'd also like to know if one of the wires for the gas valve were going to the sparker or directly to the board. One of those situations where "safety for safety's sake" beats out KISS. Nothing wrong with the old pilot/thermocouple systems with a fail-safe in the gas valve, and if whoever killed the old valves did it because of Global Warming, that unit probably wastes more gas over its lifetime waiting for the sparker than a pilot light.

[@w.miller7282]

Great job Steve, I’m assuming the board was covered under warranty since the furnace is less than 10 years old ?

[@jimmyday9536]

The board probably wasn't bad.

[@WBBClips]

I wouldn’t have been as happy as this guy supposedly was. He left in a bawd I didn’t need then chawged me for it. Not only that, it’s a new system that he put in a couple years ago with pawts going out already. Piece of junk.

[@johnwalker890]

Good job Steve.

[@yellowdeer7163]

This was a good one Steve. Wow, that was a head scratcher for sure.

[@hangngoaigiare]

dont work on ruud a lot but this is a weird one. gas valve fail prevent the board heat sequence instead of the heat sequence still happen and stop at fail gas valve. I will jump that pressure switch any day for testing it. Last time I had a gas valve fail that blow up the 3 amp fuse to the circuit.

[@davewolfy.5932]

[@deanmartin1966]

[@tomjohnston2998]

I had the exact same problem on a 5 year old ruud as soon as igniter started it would restart turned off gas valve and igniter stayed on

[@scottk0623]

I had my money on the board too, it would be interesting to talk to their tech support and see why that happened. if it was easy everybody would be doing it.

[@pedroveloso9707]

11.45 multimeter, new valve says 6.59 M Ohm (open state) , and the old one says 81.8 K Ohm, that scope is auto range just left to de ohm, it have leter M and K or nothing just ohm. this is the 3 scales Mohm, Kohm, and ohm. to much impedance of the valve, I believe that have some smal eletronic inside the valve. cheers ... :)

[@blasttapes]

Nice catch on the meter readings, Pedro! Granted, this video is only 5 days old but I love how you appear to be the only one so far that mentioned the 'M' and 'K' indicators on the meter! There's a big difference between 6,590,000 ohms and 81,800 ohms! I had a similar problem with a 10 yr old Goodman furnace that toasted a gas valve last year. The old one read 1.3K ohms and a new one read 5.6M ohms (very close to Steve's "good valve" reading of 6.59M). Later I took the old (reading 1.3K ohm) valve apart and one of the four bridge rectifier diodes was shorted which caused the 1.3K ohm reading. Literally a $.05 diode replacement restored the valve, which beat spending tens of dollars for a new one! Good eye, Pedro!

[@johnbernier1025]

My Contractor, who will not return my calls, installed a brand new Ruud High Efficency Gas Furnance in my attic. I live in Massachusetts and now I'm afraid the Heat exchange coil will freeze as the attic does not have insulation in the rafters, just the floor. The attic will get cold. I'm beyond upset with this guy and he is not returning my calls. Blown in insulation for the ceiling rafters is going to cost me $10k! Are there any other options, besides replacing this brand new furnance? I read about "change the controls to run the pump for the coil constantly when the COIL temperature (not attic temp) gets below 35 degrees, and cycle the fan as a function of the room stat." or using glycol? Any suggestions would be greatly appreciated.

[@stevenlavimoniere]

a gas furnace does not have any water in it / hot air furnace .... but the condensate drain line will freeze up and not drain i would suggest you cover it with insulation that might help maybe cover the condensate line with roll out insulation not sure how your set up is ... you might be able to put a electric heater up there when its really cold out to stop freezing ....dumb move installing that high efficiently unit in attic .. the contractor should of warned you of protectoral issues in cold weather i would not have done the job .. you should take him to small clams court .

[@ErikEisenheim80]

Hi Steve! Long time viewer of your videos. I really appreciate your work. I know it probably adds a lot to your day to have to set up cameras and adjust viewing angles while you’re doing all of your repair and maintenance work. I have a question for you: Could you let me know what equipment you use for your videos? I’m thinking about launching my own channel centered on my marine/ reef aquarium hobby. My first video would chronicle how I go about setting up a 500 gallon reef aquarium set up with a refugium. And I’d like to use a similar filming style to yours. Also, how many cameras do you use? And what are the details on those cameras - brand, model etc.

It has always been my experience that the voltage across a closed pressure sw is always 0. You stated you had 27 vac on both sides which means pressure sw never closed. ???? Additionally, shouldn’t the board and valve been covered under warranty???

[@DF-zp1os]

He had his ground lead on the frame or metal portion of furnace. He than checked at the pressure switch which showed voltage on both power tabs of switch indicating the switch passed power through. If he had moved both meter leads to each power tab it would've showed 0v or at least very little voltage difference.

[@alanleelitvin4899]

@@DF-zp1os that’s not what I saw. He had both meter leads across sw contacts. Should have been zero if closed. Even if he grounded one meter lead as you say, the voltage would have had 27 vac on one side only before sw closed and zero on both sides when closed.

Thought your original troubleshooting was great, very strange that the board wouldnt bring on the ignitor since you would think it comes first in the sequence of events. Edit: just finished the video out and realized it was a spark instead of a HSI, makes a bit more sense now.

[@BlisterHiker]

That was weird... Disconnecting the valve should never allow ignition to start. The board apparently has a bug in its software, and first of all, it should have a *LED* to signal *error codes* like just any modern control unit has. Current sensing should be a standard feature. Too bad there was no LED blinking the error code.

[@DiverCTH]

Depending on the age of that board design, it might not be the programmer or the board designer's fault. You should hear some of the folks with electronic design channels going off about bean counters and Pointy Haired Bosses telling them to cut a $0.001 part out of the design to save $100 per 10,000 units in manufacturing costs on a product that's selling for $500 per unit. Fucking MBAs.

[@BlisterHiker]

@@DiverCTH True. Almost everywhere you look, someone's trying to reduce costs, but when safety is directly at stake, such cases should land as class action lawsuits or recalls at least. There are examples of such cases in various industries and it almost makes you like lawyers, when they are on the side of consumers.

Yep if a safety was in effect it should have given an error code. Made me think the board and the gas valve were both bad.
