All this means is that the Copeland monitor is sensing amp draw on the compressor but it is not detecting a Y signal calling for the compressor to run. If there is no problem with the contactor and equipment is running fine, check for the jumper wire that carries the Y signal over to the compressor monitor.

Why isn't my Heil HVAC system working. If I override the thermostat the air handler works but the compressor doesn't. There's full voltage 240V at the compressor and air handler.


The comfort alert control modules fail and will not allow any action to the unit. I've bypassed them and it worked fine but then you don't have that safety to lean on. The alert senses high or low amperage/voltage to the compressor (if I recall correctly) only. If you have 24v to the alert module, and you have allowed time for the delay to pass (usually 3-5 mins), and the module is not sending 24v to the board, then that module has probably given up. If you have 24v at the board then the problem is at the board or one of the safeties connected to it. I've had the sales rep and the parts house manager both tell me that the alert module is a poor design. Its just as simple to bypass the alert and install a delay on make/break timer unless its still under warranty.

I need help troubleshooting my Heil home HVAC system. The system worked fine at the end of last year.


sounds like a bad contactor if you have 24 volts at coil and does not pull in. by manually holding contactor in you are doing what the contactor is suppose to do with 24 volts applied.

It is receiving a low voltage signal from somewhere else. Its powered by 24volts. And its receiving something less than 24volts (like 16-20v) but its enough to build up enough to want to pull in the contactor. I've seen it before but can't remember what the cause was. Could be miswired somewhere or a fault at the t-stat. If it has a circuit board they can get a gecko or bug behind it and the metal cabinet that can cause a "short" that will allow voltage to flow through and power the circuit that feeds the contactor.

Cant turn off my air condoner it is on auto cool ive tried reseting it but dont work


You have one of two problems. Either you are shorted so the AC continuously gets power Or the compressor contactor has welded shut and will have to be replaced. If this is a split system with a separate air handler and condenser then it is a simple check. Turn off the breaker for the air handler and if the outdoor unit is still running then more then likely the contactor is bad.

I have an error code on my american standard model # ACONT900AC43UA communicating,programmable comfort control. Says to find the Error codes from American Standard Pub 18-HD32D2-8 but I don't have...


I am experiencing the same error code on my American Standard AC and according to Public. #18-HD32D2-8, error code 126 is in the Equipment Change Alert Group and the description says "Equipment does not match value stored at startup." Then, in a footnote, it says "A device has changed since Auto Discovery (See Installer Guide *S& 0706 to reset)."

This is all Greek to me so I'm calling my AC guy. I can tell you this, however. I bought an American Standard AC brand new just two years ago and one year ago exactly, it blew up. American Standard replaced it. Now, one year later, more problems.

I question the quality of American Standard and would not be inclined to buy this brand again.

New copeland compressor wont start


Hello,By all means install a hard start kit on the cap.Your wiring is correct.A scroll compressor usally doesn't need a start kit but I have seen 5 ton units that take one.Check the compressor tag and make sure the compressor is not a 3 phase motor!

ohm out the reversing valve coil, ohm out all wires to eliminate shorts, change wire if needed, you have a short issue, unwire all wire and connect on at a time to find out which wire is causing the problem.

Your contactor points could be welded together and not releasing. Turn off breaker again and open the electrical cover to condenser and inspect the contactor. Look for blacken or fuzed points. If they are then get a new contactor let me know if you need any help and will get back to you. ken
