Ok, it can be two things.

  1. The outside unit needs to be washed with a water hose to rinse any dirt and debris that can cause a restriction in airflow over the outdoor coils. If they are allowed to get dirty, they can cause the compressor to overheat and shut down on thermal lockout.
  2. The unit has a small refrigerant leak and the unit doesn't have sufficient refrigerant for the system to run thus causing the compressor to shut down on thermal lockout. The problem with this one is that generally the inside coil will freeze up and you will notice that.
Compressors generally won't come on at all if they are bad. You can have a compressor go bad and still be running, but it won't cool at all. A bad install can cause a compressor to fail as well. Generally if the compressor fails within the first 10 years, you can bet it's because it was a poor install. This means that a proper vacuum wasn't pulled on the unit before initial start-up. Hope this helps.

Hi.

Here error codes:ERROR CONTENTS

Here a complete service manual.

Here user manual.

Before doing anything else, power down the main circuit breaker, so to power down each unit and reset the electronics in the whole system. If all units have gone down at the same time, this will often solve the problem.

Regards.

Ginko.

My Coleman furnace 4322/729 model lights the pilot but won't cut in . What could be problem ? Cleared lines Complete


Gas valve not opening? Does it have the exhaust blower that pulls vacuum switch allowing burner to light?
(1) Thermostat not working? Has to complete the circuit in or gas valve to open.
(2)Can be a stuck or bad gas valve. Try tapping the side of the gas valve body while thermostat is calling for heat. Tapping,not pounding. Like lightly,yannow? don-ohio (:^)

Why does my home A/C unit result in a constant stream of water coming out of the overflow drain? I've had the same unit for 5 years, and it seems that it drains water in ever-increasing amounts. Als


Sounds like it is freezing up. Kind of hard to say since you did not say whether it is a central heat and air system. My overflow was constantly draining onto my patio from overflow. I crawled up in the attic and followed the pvc pipe where it came in from the outside and closer to the central unit in the attic I drilled a hole in the 90 degree elbow of the pvc and unclogged the pipe which was frozen from running so long. Then I covered the hole with silicone. no more leak coming from overflow

How do I fix my electric heater


  • sounds like the sensor or bulb that tells it to start the blower is defective/ im not familiar with your unit but this seems the most logical answer most furnace will not turn the blower on right away usually 90 seconds after the ignition but will also run longer to exhume any dangerous carbon monoxide. Electricic heaters are different. What type of unit do you have

Electric Furnace stopped running


You have one of two problems. Either the capacitor for the motor has failed or the motor has failed. I would turn off the power to the unit and see if you can locate the capacitor and remove it. An ac supply or electrical supply house can match up the capacitor. This is relatively inexpensive. Otherwise you will need a new motor.
