42PQV030X/38VYX030X spontaneously switches off or from cool to heat

My air conditioner recently had its control board replaced, and is now out of warranty. Since the replacement, the unit turns itself off spontaneously, or sometimes flips mode from cool to heat. Any easy fixes?

SOURCE: Air Conditioner malfunction

Hi, Sounds like you have a short in the control circuit to me. Turn off all power going to the unit. Write down or otherwise mark the wires leaving the control board going to the thermostat. Remove them from the control board. Replace the fuse. Turn power back on and see if the fan still runs. If it does, check and or replace the heat limit switch that brings the fan on during the heat cycle. It may just need adjusted. If the fuse blows, I would think that the control board is probably bad. If it doesn't blow, Remove the thermostat. Leaving all thermostat wires open check them with an Ohm meter. There should be no continuity between them. Twist all the wires together at one end and ohm them again at the other end. You should have complete continuity on all wires. If the wiring checks out, down power the unit. Double check your wire colors and rewire the control board. With all wires open at the thermostat, turn the power back on. Touch the RED wire to the YELLOW wire. The Condensing unit should come on. Touch the RED wire to the GREEN wire. The fan should come on. Touch the RED wire to the WHITE wire. The heat should come on. Down power the unit. Replace the thermostat. Test unit. If the fuse has lasted ok but blows now it is either wired wrong at the Thermostat or the thermostat is bad. I hope I have helped. NOTE: If you can not understand these instructions. Call a licensed Heating / Air conditioning company. kstfas

SOURCE: I can't change the fan mode to cool mode.

Go to the manufacturer website and try and find their download page for the manuals or literature. If they don't have a download, you will have to contact them either by phone or email. They should be able to mail or fax you one.

If you are talking about the indoor fan it is probably a bad capacitor. Replace the fan motor capacitor. And YES, if the fan motor needs replacing too, you can DO-IT-YOURSELF.

No heat but fan keeps running


If the air conditioner compressor runs all the time the main control board might be defective. The main control board provides the voltage to the fan motor and compressor. These boards are often misdiagnosed. Check all other components to be certain this is the cause of the problem.

This is a heating and cooling through the wall heat pump. It works normally when heating is selected - the heat pump runs and both speeds of the fan blow warm air. But nothing runs when cooling is...


You have a bad board or bad switch. I would say board. You can have service tech check this out. There is only so far you can go without knowledge of Controls ad electricity. Russ

A/C starts, goes immediately to heat


Unfortunately, your rear unit is calling for heat. If you put the rear unit on heat pump mode, does it then cool?
moz-screenshot-2.jpgmoz-screenshot-3.jpgThe reversing valve is energized in the cool mode of these AC's. So there is no real way to bypass it. I would check the thermostat and the control board in the unit to make sure that the switches are set correctly.

In the service manual section of the dometic/Rooftop RV Air Conditioner section. I have posted service manuals for the Heat Pump and the Comfort Control.

Hope this helps,

Jeff

Mitsubishi MSH 18NV no heating or cooling


The fact that nothing is coming on indicates that there is possibly a problem with your incomming power supply or wiring to and from the inside evaporator to the outside condenser. If all in good order, suggest you find someone you know who can operate a multimeter and check if there is voltage going to the control board inside the evaporator unit. If there is then almost certainly the control board would need replacement.

Thermostat problems


Have you confirmed that the thermostat is programmed correctly?

Did the thermostat ever control the temperature of the house properly?

When you indicate "kick", are you talking about flipping the Auto-On switch back and forth? The Auto-On switch only controls the fan, and no heating or cooling (Auto - fan runs on call for heat or cool, On- fan runs all the time.).

If "kick" means making the heating work, and if you have the same problem for making the cooling work, chances are good you have bad thermostat.

If the problem only occurs with the heating, and cooling works fine, then the problem could be in the controller board of the furnace, assuming you have a more recent (1990's or newer) furnace.

GE Room Heat/Cool unit will not heat with heat pump


If it was me I would cnage the sensor first. Simply because it is way cheaper than the control board and these sensors are fickle as hell to begin with.
