Question about Intertherm P3RA-048K Air Conditioner

1 Answer

Intertherm heater blows cold air.

My AC works but the heater just blows cold air. It started last night and when I woke the house was in the low 60's and the thermostat was set at 72, the heater ran all night.

    My A/C is two years old, the thermastat was provided by Austin, Energy. The outside unit is old but seems to be responding just fine when the A/C is on Cool. Turning on hot and it just blows regular to cool air and the outside unit doesn't respond. I have cleaned the blower and wire connections. There is no standing water of any kind and I flipped all the circuits inside and outside of my building. Why would a A/C not heat but cool just fine is my questioin?



    Thank you.

Good evening all, This morning woke up to my home


Sounds like a faulty Tstat that's sending a low voltage signal to the contactor coil only sometimes. The high pressure cut out or the compressor's internal thermal protection could of opened, and then closed again after cooling. Make sure the condenser is clean and not obstructed.

The Intertherm AC Model B3BV-030K-A is blowing warm air


If you don’t see any frost on the suction line or big line on the furnace
(that goes from the furnace to the outdoor unit) and the filter and coil are clean then you are probably low on refrigerant.

MY HAIER A/C IS NOT GETTING COLD


I have a fairly new Haier Air Condition that I bought last year, it has been working good up until last night. I keep this one in my bedroom and put it on every night since the summer. Last night I woke up very warm, the temp reading was 75 the AC did nothing but blow out just air. I threw away the booklet on it because I've had no problem up until now. Does anyone know how I can make it cold again. HELP!!!!
