Question about Weather King 12AJA4801AH Air Conditioner

2 Answers

Weather King AC/Heat Pump - Electric unit, Model 14AHJ11S01C01

Ice formed inside restricting the air flow but heater was still producing warm air; main power switch was shut off (circuit breaker looking switch on the front of the unit) while we began thawing the ice. 90% of the ice is gone and air is now flowing to the rooms, but now it will not heat up / produce warm air.
This happened one other time, a year or two ago, and I know it did not require major repair but I do not know (or just can't remember) what was done then to make it start producing warmth again.
Thanks, AJ

    My unit's compressor has frozen up several times too and the fan runs steady and won't shut off.

    My problem is with the cooling though.

    The heat was cut on to defrost the compressor so the air conditioner would start producing cool air again but cool air blows through the vents only for a few days and then warm air comes through the vents again.

Your evap coil in your indoor unit should not develop ice in the heat mode. It sounds like your reversing valve may be stuck in the cool mode, not allowing your heat function to work. If it is cool where you are you may need to use your emergency or auxillary heat function until your problem is resolved.

Carrier fa4anf036 home heater not a car. Blows luke warm common for an electric heater?

As near as I can tell from internet information. This model is a heat pump. It transfers cold air out of the house and gets what ever warm air might be outside the house. In extreme cold weather an auxiliary electric heater should make up the difference. The filters must be clear. There is a limit what the heat pump can do in cold weather. Your electric heater may not be activating. You could try raising the thermostat. A service technician may be needed to determine why the electric heater is not working.

Water leaking on the floor. The unit cannot be opened to empty? What is wrong

Check to see if ice is forming inside. If so, check filter. Blocke filter restricts air flow and ice builds up on coils then melts slowly with heat from room.

The outside fan may run if the unit is in defrost mode this is normal for most heat pumps it is there way of trying to keep the outside unit from staying iced over so the next time the unit runs it will have air flow through the coil and the ice will not be there to prevent air flow.

Defrost cycle is to allow frosy or ice to melt down and not restrict the output air. The thermostat is set too low and in high humidity ice forms quickly restricting the air flow. tur up the thermostat and let the room cool gradually.
