Question about Carrier 38BRC036 Air Conditioner

Carrier air conditioner cycles on and off

This winter, my furnace suffered a power surge. I had to replace the board in the furnace. I am not sure if this relates to my current problem, but my issue is that my Carrier air conditioner keeps cycling on and off. The thermostat kicks it on and the air conditioner cools the house just fine, but when the thermostat is idle (i.e. the house is at the set temp), the air conditioner outside keeps kicking on for 30 seconds every 7 minutes. While on, the fan in the air conditioner (and I believe the condenser) run, but there is no air movement inside and no reason it should be on. (The furnace and thermostat remain inactive). The only way I can stop this is to shut the power breaker to the air conditioner off. I do this while I am away. Any idea what the issue is?

The compressor/condenser is being called all the time. The reason it goes off is because the evaporator (indoors) freezes up when the fan is told to turn off by the thermostat. This further cooling lowers the low side pressure below the low limit switch point turning off the compressor unit.
Solution: Make sure the thermostat is wired correctly. Green wire is usually the compressor wire but maybe not.

If you're sure the igniter is good and the controller is sending voltage to gas valve to open, but not to the igniter then, yes, the controller is bad. The only way to know for sure is to remove the igniter's molded plug from the board and test voltage directly at the board. You should get about 100-120 vac to the igniter.

Outside unit won't run


If the inside unit is running properly, there will be a yellow wire (or blue) from the thermostat down in the furnace that needs to be hooked up to the Y terminal also there is a red and white wire in the same place in the furnace coming from the outside unit, one goes to the Y terminal also and the other would go to the C terminal in the furnace. Otherwise you may have a bigger problem.

Gas valve lockout


It means that the furnace isn't igniting and for safety the control board is preventing the gas valve from opening. Turn off the power to the furnace for a few seconds then observe what the furnace does in heat mode. Some furnaces will run the blower for a minute after you power it back up. After that see if the furnace tries to come on. If you are still getting the code then one of you high temp limit or roll out switches has tripped. Now is the time for a service tech. Make sure that you check you filter and air flow too. Low air flow means the furnace may be over heating.
The other thing is the hot surface igniter. Look closely at it with the power off. Do you see a white spot on the element or a crack. If so the HSI is bad. It's an easy replacement but DO NOT touch the carbon element with your fingers and be very careful handling it as it is EXTREMELY fragile.

(HVAC) Furnace Not Igniting Quickly


Make sure a back draft in the flue is not happening. Wind can blow it out until the flue heats up. The flame sensor may not be close enough to the burner flame. It may be weak and need to be replaced or if its an optical one it may be dirty and not see the flame very well. Its not wasting much gas but it puts extra wear and tear on the gas controls, is noisy, and, as you said, blows cold drafty air. A gas control system that has issues of any kind is not real safe. It needs to get fixed.
