I'd say the right one was replaced/failure/burnout. left likely original. possibly a brownout or phase loss/brownout, banged the fuse. even the wires were all rubbed out, none looked to have shorted. the overheated(blown) fuse could have been poor disconnect contact, either tension loss on the blade or the fuse holders. many had hardened spring steel clips that fail with rust, and age from thermal cycling, once tension is lost game over. that happens often on circuit breakers also, at the end which plugs onto the bus bar, when it breaks and loses tension it start overheating and cooks itself, usually wrecking the breaker case and the panel bus terminal. (aka new panel time)

Great video as always! It would cost like $1 to $2 for the manufacturer of the lockout boards to add LEDs that indicate incoming call, outgoing call and a lockout situation. Add $1 more and you could have two color LEDs that gradually switch color to indicate if a call came within the last few seconds, or a lockout happened within the last few second. Not sure if it would had helped in your particular case, I didn't get which order the lockouts and the economizer control thingie are hooked up, but still. P.S. an argument for repairing instead of replacing is that some parts are fairly new and those that have survived for 20 years are probably good enough to survive almost until eternity.

Mister, you are one Hell of a troubleshooter and technician; I hope your customers realize this when you talk to them about repair vs replacement (even in CA). You are going to get another call on this same unit (I'm an old 'motor man' and, yes, change the blower motor if they'll let you and 'stiffen' the base if you can). Very nice work on repairing, rerouting & securing the control & power wiring (somebody else has been there before you). Ah, and SPARE 60Amp Fusetrons; Abondanza, Brother!

I love how you inspect as to why a fuse blew. Many just replace it. Sure something like a rolling blackout or brownout can cause a surge but if not known it's good to try to find out why. It's not always possible and the should call back if something happens again then you know for sure there's a deeper issue that wasn't found the first time.

None of them may have been enough to take it down on their own, but if a couple had it right on the edge already any little thing could have tipped it over.

Here in Maryland, It’s not unusual to see Restaurants Milking a RTU that is 35 to 40 years old. The Request will usually be they want the Unit repaired and how much. What usually forces their hand to replace the RTU is Water intrusion, Compressor failures coupled with known Refrigerant leaks. That seals the deal every time. Good Video.

Got an evaporateor change out on one of these next week. Multiple techs have been in this unit over years. It was way over charged, no one seemed to diagnose the plugged accurator's. Low suction add gas. Customer doesn't want to pay for R22. Looking at R422b. If i remember correctly that's like a 10% loss in efficacy. You mentioned not using replacements on a fixed metering device. Compressor has been changed I'm going to dump the compressor it seems like there's too much oil in it. Dripps out of both ports.

Interesting and informative video, Chris. That RTU looks like it's been patched up and modified numerous times making it a pain in the proverbial to determine if something is what it appears to be or the result of a 'creative repair' in the past. Regarding the low voltage side, why not get some 24V AC/DC LED indicator lamps and put clips or backprobes on them? Some of these indicator lamps are prewrired and need only suitable termination of the wires. Careful positioning in the circuit would show exactly what is happening and when as well as where any issues occurring. If a camera was set up you would then be able to easily prove what the problem is and what needs replacing to remedy the situation.

Older units like that one generally are a menace to keep running past 18-20 years due to parts and other things not being made anymore. Just be glad it isn't pouring water into the building! had a residential AC unit in a home i use to live in had it's coil drains fail, where something came loose and plugged up a pinhole drain. Flooded the entire lower level one week and the military housing people didn't want to fix it. Long story short, we got a new floor and a new unit with proper installers after some angry phone calls to managers of managers.

Those Carrier units have a collector tube that ties all the evaporator coil distributor connections to the coil together.. I have connected the condenser liquid outlet line to the evaporator line with a txv if the unit is cool only or a check valve and a txv if the unit is a heat pump. It is a fairly easy work around to put a txv in parallel with the defective fixed orifice s and bring the subcooling down to normal

There are several videos from other HVAC guys who show in detail how to they free up the accurators on these evaporator headers. I've done it myself with total success. The labor is still going to be high for the work involved, but it can be done without having to completely change out the evaporator. Some even have TXV's kits available and you can ditch the accurators alltogether.

Whend i faced so many trouble in unit like this case, i going to do some mechanical integrity checking. If its low the whole unit is going to down often, because the components has disturbed and no chance to do their jobs well and it always causes non-critical isues that way. But when these isues are comeing and going the components gets stressed by eachother and its going to fall most non predictable ways. This is can not be slow down effectivly without get an aceptable mechanical isolation inbetween the problem-sources, to get find them in the usual easy-to-understand work OR not work states. When is achived they going to act as an old component, and start to do their jobs realy well. In this case is lot of effort but take mutch less time compared to fight the seemly “not critical issues”.

22:30 mechanical electrical joints like wire nuts arent designed for the kind of vibration seen here. Lots of poor design in wire routing and termination shown in this unit. Really cool stuff, thanks for your content.

I am having thoughts of the Jade located in the blower section is an issue. I have seen a similar issue on a handful of them that are in the blower area and none that I can think of in the controls section.

I think it is less of a problem of it being in the blower section, and more a problem of it existing at all! All 3 I've found doing strange things this year were in the controls compartment.

Very nice running that problem down. I had a couple newer Daikin RTUs in June with similar set of issues, I thought it was the Jade controller too. Ended up being a bad factory 9-pin connector to the Jade controller, even having the bypass plug in would occasionally chatter the contactor and trip the breaker. Intermittent electrical issues are the most difficult and fun brain teasers of this trade, imo. I probably condemned myself to another one next week having said that. What are you using to measure the airflow in MeasureQuick?

I had a similar issue today, blank Tstat caused by a tripped breaker. No popped fuses though. I went through the entire system and all I found were a couple of low voltage shorts via wire rub-outs; one was from the defrost termination switch and another was a pressure switch. Not sure how that caused the breaker to trip and not pop the fuse on the board, until I saw that the transformer was tapped wrong. Was tapped for 230 instead of 208. I corrected that issue too, then wondered if maybe that caused the contactor to chatter which could trip the breaker. But the contactor wasn’t burnt up or pitted. One of those weird things that kinda stumped me, but whatever the unit is working fine now. 😆

How about dust proofing the disconnect (and the other electrical compartments)? You could for example slightly pressurize those compartments with air from the indoor blower.

While I've never worked out in a sandy desert area, I do have a cement bagging plant I do service for. Nothing, and I mean NOTHING that isn't solid state and/or hermetically sealed is dust proof! Also, if it is an electrical enclosure located outside, and is sealed up almost but not quite perfectly air tight, there will be condensation inside the enclosure.

If the 2nd fuse to blow was the same one that blew before and was the disconnect knife that's making a poor connection, then the fuse likely blew because the bad knife connection is causing it to heat up and if it gets too hot, the fuse will blow thinking it's passing too much current... Fuses are micro-heaters at heart, the more current they pass, the hotter the fusable link inside them gets and when they get too hot (because they're passing too much current), they melt and a spring pulls the two halves apart breaking the circuit, too much heat in a nearby component (such as the knife blade half an inch above the fuse) will also cause the link to melt, blowing the fuse... When the fuse blew, cutting only 1 of the 3 Phases, it likely caused enough of an Imbalance in the Main Breaker to cause it to trip... In addition to that, I suspect you also have a failing (or outright failed) Jade Module and/or Compressor Lock-Out Board... That's my Theory, though I admit, 3-Phase Equipment, Breakers and Fuses are not my Specialty as an Electrician, my Training and Experience has always been in Residential Wiring...
