Defrost Cycle Problems with Weatherking Heat Pump Model 10PJA4201

Thanks for your answer, that's what my operators booklet also said, however I don't think that my board was wired up correctly by my installer who is already out of business, when i first called for a service call he said that it wasn't cold enough for it to work, after another call when it was colder, he was ugly about me calling again, when he came I was watching, I think all he did was short out the test pins which made the unit go into a defrost cycle for a moment and right back out, our winters haven't been very bad, so being almost 70 at the time I've just lived with the problem. I looked at the board today it has 13 different wires attatched, where might i get a wireing diagram so i can be sure if all wires are properly hooked up, my book said that by changing a wire it would change the coil temp, from 50, 60 ,70 or 80 degrees, so if i can down load a diagram maybe i can fix it with out buying a new high priced one. The nos. on the board are Rheem 47-21517-14 0128-05
THANKS for your responce

BUZZING NOISE FROM MY HEAT PUMP


Take a look at this YouTube page that explains with good videos what are some of the common problems with heat pump noise. The one that seems dominant is the defrost cycle a heat pump goes thru when it melts ice off the evaporative coils. In defrost cycle, The compressor runs but the cooling fan does not, so you will hear a loud buzzing sound and the unit sounds like it is stalled...because only the compressor is running to generate heat to melt coil ice.

Rheem heat pump not coming on in heat mode. Control board has two LED lights # 1 solid, #2 blinking. What does this mean?


Usually wen the led lights are blinking it means there is a problem. If you look on the door or the cover there should be a code that tells you what the blinking represents.

Example - one blink per second - compressor, two blinks - fan motor, etc. The other thing you can do is look up the model number on line for the installation manual and it should have all the info you need.

HEAT PUMP PROBLEMS


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.

Tempstar heat pump: want to bypass defrost thermostat


Don't attempt to bypass defrost mode. If it's cold enough to use as a heat pump, it's cold enough to need the defrost cycle.

It sounds like a sensor issue, although it may be the controller board.

Unless you know how to work on equipment like this, I urge you to get a professional to service the unit for you.
