Having problems with your Air Conditioners ?

My outdoor heat will not operate. It is a Carrier 38YRA042330, with a Carrier Thermidistat thermostat and a Carrier Air Handler 40FFKB005300. I have an H5 error code on the thermostat will I put it in Heat mode and raise the setting to call for heating. I changed the air filter on the air handler when I realized the heat pump was not operating. The air filter was pretty dirty. The system will operate in aux/emerg heat mode, with the fan in Auto or On mode, and will maintain the thermostat


Answers :

You need to go oside and look for a red reset button on the unit. you tripped the high ressure switch when you let your filter get that dirty. go check on this and when your done if it still is not working then ask me more.

Intermittent heat I have a Carrier (Payne) unit (FA4ANF030) with intermittent heat output. The air works as does the fan when in heat mode, but usually no heat. Sometimes it will suddenly begin to put out heat normally and will function fine...until it doesn't. The thermostat was old, so I replaced it first. Seems to make no difference at all since it works exactly as before.


Check wiring of heater, it may have loosed connection or corroded connection. ... Air Conditioners

Carrier air handler pulsates even when not heating, stops only when I unplug the unit. operates okay when I turn up heat, but continues to "pulsate" even after I turn off the heat at the thermostat

Thermostat setting I just bought a new house and I have a heat pump-we live in North Carolina. The name on the thermostat is Braeburn and it is a multi-stage 2 heat/ l cool digital thermostat. We have it set at 68 and when the blower first comes on it blows warm air-however then it switches to cool air. And sometimes cool air comes out first. We have set both stages to 68 and it is in the heat mode. Should the 1st and 2nd setting be different?


What i would do is see if the outside unit is working at all. when you first turn it on the air was warm due to the fact that the temperature inside was cooler than the set point. when it get within 2 degrees ... Weather King 12AJA6001AH Air Conditioner

I have a Carrier Debonair 250 thermostat runs my AC and heater made by Carrier. it continues to run past the SET heat setting of 68. One day we were not home it continued to run until 99 when we stopped it and temperature was set to 68. When I leave it in AUTO mode (heat 68 and cool 70) it will run both heater and fan/ac continuously without any interruption. It did this for more than 4 days. Since then we are manually operating this. Is this my Thermostat that is bad or my system is bad. Please

A Nordyne air handler, model B3BV-030K, with 4 wire thermostat. Thermostat and AC works fine in "cool". Switch it to "heat" and nothing happens.No fan, no heat.(I have built in heat strips -resistors). I jumpered (on the nordyne circuit board-input from thermostat) from R to W. (24 volts from R to W, which should start the heater. Nothing. No relay "click" like when AC comes on. If i jumper R to Y, AC comes on ok. Does this sound like a relay gone bad on the circuit board? Or what? If relay bad,

After a cooling cycle, when the thermostat call for more cooling, it take up to 5 minutes after the air handler starts for the compressor motor to restart. The top fan operates on the outside unit, but since the house is not circulating cold air, only the room tep air the house heats up about 3 degrees before the compressor comes back on and cool air begins to come from the ducts. Yes. I know there is a safety feature to protect the compressor, but can the cycle be shortened?


No, this cycle cannot be shortened due to the simple fact that this feature is in place to protect your system. Even if it could be, I wouldn't recommend it.Mat ... Coleman Air Conditioners
