Can you advise? Trying to fix my daughter's furnace. Our furnace guy is too busy. It's not high efficiency like the one in this video. The motor in the "draft inducer" blower motor burnt out. Got a replacement from Amazon yesterday. The original blower housing has a small 3/32" steel tube port for a silicone tube that goes to the pressure sensor. The new blower doesnt have that port so I made one with a rivit nut and a hollow 1/4-20 screw but the pressure switch doesnt click. I assumed that since the port is outside the squirel cage wheel, the pressure switch must sense positive pressure. It doesn't; it senses vacuum! When I suck on the disconnected tube to the pressure switch, the furnace comes on. I dont know how there's a vacuum inside the blower housing but outside the squirel cage. Maybe there's some kind of bernouli thing going on. The blower mounts to the exhaust of the hot box. Its outlet is blowing vertically upward to the chimney at a tangent to the squirel cage at the 9 o'clock position. The vacuum port on the old blower was on top at the 12 o'clock position. I didnt think that position mattered so I installed my new port at the 3 o'clock position. The smoke from a blown-out candle is not deflected by my new port when the blower comes on. I'm about to install a 2nd port at the 12 o'clock position today. Do you think it will work?

@@Bluuplanet Since this was 9 days ago, I assume you got it figured out. Pressure switches should be called NEGATIVE pressure switches or vacuum switches. I cannot think of a single furnace (except the Lennox Pulse) that monitors any kind of positive pressure. The placement of the port on the housing would be critical.

@@chrisdeanndavison3626 Its operational but not fixed yet. Furnace man was swamped; said if we could get it running any way, do that and he's coming when he's got time. I figured the switch was negative when I had to suck on the tube to make the furnace run. Since it's a brand new blower, it's dependable till he fixes it so I shorted the N-pressure sw for now. Think I got the port in the same place but it's about 5/16" OD and the original was about 1/8" OD.

This was an exact replacement for the old one that lasted about 10 years. kzbin.infoUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh The top of my mitigation tube by my roofline was just a 90 elbow which allowed too much debris to fall down into the fan, eventually ruining it. Without this issue, I bet it would have kept running another 10 years. When I replaced this fan, I added an extra elbow joint so the top tube now it does a 180, which should solve that problem. The radon guys around here wanted to charge me a $300 diagnostic fee, then parts/labor (probably close to $600 total). I installed this all by myself in about an hour for the cost of the fan; it would probably be even easier/faster with two people. FYI the manufacturer's warranty greatly differs depending on whether you install it yourself (1 yr warranty) or have a licensed installer do it (10 yrs).

On the newer style furnaces the burners are kind of like flame guns. Anyways there is a narrow slot at the burning end of the burners that can sometimes get dust or carbon buildup in them. This causes the flame to not jump across all 3,4,5or6 burners so on. This in turn never reaches the flame sensor and causes shutdown. You see this when it happens if your watching the burners.

Good video should help a lot of people. I’ve successfully serviced furnaces myself for quite a few years with no training. There’s really only so many components to check and things to go bad or get dirty. Identifying the failsafe switches is important. The only parts I have ever replaced over the years were thermocouples and 1 circuit board that got water damaged from a missing stack cap. Everything else was a result of being dirty or corroded and cleaning cured it. The most common problems I have come across were thermocouples and corrosion on burner circuits preventing ignition. Something anyone with a basic understanding of how things work can service I believe. Just gotta use your head.
@teegees8 ай бұрын
Hey, thanks for your comment on this. I'm now thinking my problem is also with the thermocoupler. I got a brand new flame sensor just to rule out an issue with the old one. Basically, the cycle gets to the flames, and even the blower, but then the flames go out, with the blower continuing, I took out the burners and made sure they were clean and didn't have any air leaks, but that didn't change the situation. Also the control board was replaced only a few years ago so I don't think that's the issue either. What do you think? Do I just need to replace the thermocoupler?
@bensk8in4678 ай бұрын
@@teegeesIf you think that thermocouple is even just 5 years old, for the money especially, I would replace it. They’re pretty universal and usually less than $10 at typical stores. Unless you turn off the gas and completely shut the furnace down for the summer, they have a constant pilot on them year round and they get burned down to a nub and stop working or get weak. Because what they do is produce a small amount of electricity to keep a valve open as long as they are staying hot. So if you’re igniting the burners and then everything blows out after a minute or two I am thinking the draw of fresh cool air through the furnace when the flames are burning is causing a weak thermocouple to cool off just enough to close that pilot valve and kill the pilot light. Once the pilot light is off the whole burner operation is going to shut down whether the main burners are burning or not because the thermocouple is a failsafe mechanism. If the thermocouple is in good shape though and it looks like it has it’s shape still cleaning them with a wire brush can improve their sensitivity because they can get a residue from condensation on them. Being sure the pilot port is clean is a good idea too so the thermocouple is getting a crisp rich flame to stay hot. And also it is important that the flame is hitting the tip of the thermocouple. Usually the last 1/4-1/2” and this can be adjusted as well. If you replace the thermocouple just be careful not to kink pilot gas line while working on it. They’re delicate. Use the old thermocouple to pre match the route of the line of the new it will make installation easier. I’ve replaced thermocouples with & without taking the complete pilot assembly out it just depends on how easy the particular unit is to get to 🤷♂️. If you’re having to relight the pilot though each time I think it sounds like the problem though. I hope this helps.

@@bensk8in467 hey thanks your detailed response and tips on this. Turns out my furnace has no pilot light and the igniter is a ceramic heating element which heats up and ignites the gas. Since I had already checked the burners and replaced the flame sensor I was looking to now replace the limit switch, and then the gas valve if necessary (most expensive part to replace). So far I’m just using space heaters but eventually I’ll get things working again. Thanks again 🙏

@@teegees Sure you’re welcome it could help someone if not you anyway. I did wonder if you possibly had an electric igniter. Glad you have some heat at least for now. One more thing to possibly check is if it has an automatic damper for the exhaust. Because if that isn’t opening up it would shut the flame off. They can stick and not work right if it has one. I think you have a failsafe switch issue of some kind. One thing to keep in mind troubleshooting sensors is they generally two wire & just on or off so you can disconnect the switch and connect the two wires to bypass. If things cycle as they should, you know it’s that switch and saves the guesswork. Hope you get er man 👍

One other common causes of a furnace not staying on is the filter needs replacing. The blower motors usually have a thermal protection device for when the motor gets too warm. (ask me how I know this one) One cause that will keep Step 3 from happening is the ignitor has burned through. Had this happen twice at my last house over 12 years time. Usually unplugs (two wires in the wire harness) and then be checked with a continuity tester. Somewhere there is often an LED that will flash an error code (long flashes and short flashes) and a listing of what the error code means.

I had similar symptoms in a gas furnace. Turned out the draft enducer would cut out randomly momentarily while running slamming the gas valve open/ closed. Two different tech calls later and a new gas valve the problem still persisted. So I took matters in my own hand- turned out there was a partial blockage in my chimney. I had a co detector in the same room, never went off but probably due to the draft enducer saving our lives. Moral is to clean the chimney even if all you have is gas.

It’s called flame rectification, it sends a micro amp signal to the control board and if it sends a weak signal then it won’t allow 24 volts to the gas control hence shutting down the burner sequence as part of the safety for the system !

Great video. Been there, done that. Was without heat for month when hiring a terrible HVAC firm. He started just changing parts. First the electronic control unit $500. The tried to change the gas control valve but couldn't get it off, not sure how much that was. After they didn't show up or call for a week or so, I called the original installer and asked for a tech who had helped in the past. Should have done that in the first place but thought I'd try a new company with an inspection discount. He showed up and this is the first thing he looked at, quick cleaning and started right up. He told me there are a lot of "parts changers" in the industry who will just keep doing so until they strike onto something.

Scott You are absolutely wrong with suggesting steel wool to clean a flame sensor! Using steel wool takes the coating off the sensor which is as much important as it is not to touch the sensor with your fingers. Cleaning can be done with a dollar bill or a scotch Brite (green pad) only!

@@EverydayHomeRepairs Nice video, well done. Fine steel wool is OK to use, that's what was recommended to use back in the day. However, I went to scotch brite pads because fine steel wool corrodes easily. The flame rod does not have a coating as far as I know, you want to avoid abrasive cleaners like sandpaper or plumbers roll because they will etch grooves into the flame rod material that will quickly fill with detritus leading to premature failure. A typical flame signal is in a range of 1 dc microamp to 3 dc microamps and anything that increases the resistance to the flow of such a tiny current will cause trouble. Even a rusty/dirty gas burner (serving as the ground conductor) will do it. The flame signal returns to the control board via chassis ground so if the burner is rusty or the ground wire is loose, you'll will likely have flame failure.

Notice how this furnace has three flames, with only one igniter and one sensor. They are all in a line with the igniter and sensor at opposite ends, so the fire spreads from one end to the other, and the end with the sensor can only light if every single burner lights to pass that flame along.

It’s a cold night in west Texas and my heater wasn’t working just before bed. This video helped me greatly. Essentially the cycle never made it to step 3. I took off the front panels to try and diagnose and it worked perfectly. I put the panels back on and it stopped working. Your video broke down the 6 steps and helped me understand why it wasn’t working. Somehow the tube connecting to the pressure sensor in step 2 turned and when the panels were on, it pinched the tube blocking the draft to the pressure sensor. Easy fix I turned the tube and I now have heat!
