You have to try resetting the system. First turn the breaker off for the condenser and wait about 20 seconds. After you turn it back on the system should reset.

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: heat strip installation

It was quite simple, just installing the heat strip and my model only required removing the grill cover and mounting the element. The other optional installations didn't apply to my model.

thanks,

SOURCE: Comfort Aire PAC-121 problem

E4 shows up on the screen on my PAC-121 when the water reservoir on the right-hand-side is not pushed in all the way. If it is in all the way the switch that it engages may be bad or out of place.

    I live in a very small one room studio,and have a comfort aire window unit...air and heat.The heat works real well,but in the spring and summer,I would set the unit on the coldest setting.I can hear the...


    Lets look at the output of the system first. Take your square footage of the area you are trying to condition and times it by 15. We try to get 15 Btu's per square foot of air conditioning. If your area is say 10 by 15, you have 150 square feet; times it by 15 = 2250 Btu unit is required. If you have a 5,000 Btu unit, it should be more than enough to cool the room. If this is correct, the problem may be because you have the unit set for Dry. In Dry mode, the compressor will cycle less frequently than if on Cool. If in fact the unit is on Cool, you may need to lower the temperature setting to fool the sensor from turning off the compressor prematurly. If you still can't cool the area, your unit has an issue with either refrigeration or air circulation and will need to be serviced.

    B zone is only cooling to 49 degrees and leds at L3 and L4 are blinking at 1 second intervals at circuit card on outdoor condensing unit. Is there a service manual available for download?


    Hi


    The L3 and L4 lights are blinking means that the filter is dirty and obstructed. You’ll need to clean the filter. Also Inspect whether the evaporator air is blocked, remove the blockage. Check the air intake and outlet ducts of the condenser side are obstructed. Check both of the ducts. Check whether the unit is set on dehumidifying mode. Set at cooling mode, Set at low fan speed Re-set the fan speed at high speed and check.

    However, if this doesn't help then it might have happened that the compressor is not runing and the connection to the compressor is cut. Please check the wiring diagram on Pg 22 in this manual---
