You must be having some very cold weather. Heat pumps shut the fan off when the temp. of the coils on the outside hit a certain temperature. That is to increase the pressure inside the unit to get more heat out of it. Your unit also goes into a defrost when ever it gets that cold also. But the compressor turns off also.

Now if your fan never comes on need to check the motor with a ohm meter. And check the capacitor it is a dual one meaning fan and compressor. One side can be out so need to check that also. Turn power off to the outside unit just pull the safety disconnect on the side of the house. Take the capacitor out ohm out the C side and the fan side. You will notice the Herm side meaning compressor. My guess is motor is bad. But I'm not there so concentrate your efforts there. Let me know how it goes okay. Ken

What size capacitor in a Carrier Heat Pump 38yh036300


This is a three ton heatpump must likely it is a 35/5uf capacitor. But if you can read compressor tag it will tell you size it requires and also fan label will do some for it.you will need to ask for a dual capacitor from supply house make sure you pay close attention to hoe wires hook up so you can wire in new on before removing wires make sure you have high voltage turned off to unit.take pic with phone this will help when you rewire

When the heater is on, should the fan outside on top of the unit also be working along with the blower from the heater ? When the heater is off, cold air is comming from the vent's, can I cover the


No. This is strictly a gas package unit, not a heat pump. the condenser fan motor should NOT run when their is a call for heat from the thermostat. The condenser fan only runs with the compressor on a call for cooling. Hopefully the compressor is not running @ the same time, but if it is, it would make sense that the contactor for the compressor & condenser fan motor is stuck closed OR the low voltage cooling wires are shorted straight to a 24Volt control wire.

Carrier OEM to Honeywell Programmable Tstat - NEED HELP


you likely have a "two stage" system, but not a two stage heat pump. the first stage is probably the heat pump itself, and the second stage is the auxilliary resistance heat that suppliments the heat pump at lower temps. if i knew the terminals that are available on the new stat, i could advise you on the proper wiring.

We have a carriers air con that is about 4 yrs old it has a remote control and digital readings on the unit it is in the wall we can not get it to heat but it does cool we didnt put this in it was here...


Normally all air-cons carry an identifying label on the compressor unit. It has to by law state the gas used. On a split system this would normally be on the outside unit. Sometimes an additional label will be on one of the ends of the inside unit. Some units only do cooling - you need to check once you've found information. Check your remote control 'Mode' setting is correct - it should show a small 'sun' to indicate heating. A small 'icicle' looks similar, but means cooling. Then check temp setting is high enough to cause heating.

My Grand Aire heat pump is forming ice all around the outside fan unit... Is this normal?


No that is not normal. Your AC unit may be low on refrigerant coolant and needs to be recharged. If it's low, there's probably a leak, which is causing the ices on the outside unit. Contact a qualified service technician to check & service the unit.

That is model number for your outdoor unit. Thermostats are not dedicated to any particular model outdoor unit. You need instructions for the thermostat so the thermostat make and model number are needed.

Hi, this is an odd voltage 380 volts. Is it a 3 phase unit? To get a 220 volt 50hz condenser fan motor, you will have to go through a refrigeration/air conditioning parts house and order this. 60hz you would have no problem finding one in stock. Carrier is a good unit, and have been around for many years. You shouldn't have any problems locating one.
Sincerely,

PS You will need to go through a wholesale parts house.

Carrier 38CKC042300. oUTSIDE UNIT FAN WAS TURNING REAL SLOW. ac UNIT IS OFF BUT FAN TO OUTSIDE UNIT IS STILL TURNING. sHOULD NOT BE TURNING AT ALL WITH AC UNIT OFF


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.
