Sounds like wiring issue to me. I've delt with units like this and there is a wire lead for fan only and a separate one to run the fan when the unit is cooling or heating. I'm only speculating here but I would bet money that this was improperly installed.
Dont get discouraged though because it sounds like its working (for the most part) if you feel up to the task find the manual and check your connections. Otherwise hire a professional.
There is a short somwhere in the low voltage circuit. Test the continuity of the remaindimg wires to ground, you should have no resistance, if you do have resistane the wire will have to be replaced. Also, the thermostat can have an internal short which can cause the fuse to blow.
Sounds like limit switch is tripped if all it does is start the fan. Is ventor motor running? If not check limit switch should be located below burner compartment. May be manual reset but probably not. Tap on switch and then check filter to see if plugged.
The indoor fan will continue to run. When heat pump goes into defrost the outdoor fan stops, the reversing valve switches and the unit is basically working in the cooling mode. In order for you not to feel a blast of cold air in the winter the electric strip heat also comes on so the indoor fan must run while the strip heaters are on.
This sounds like the fan not turning during cool. You will have to check the fan relay for power during the cool cycle. The fan relay is run by the low voltage side, but still there is hi voltage present. When in heat the power goes thru the relay on one set of points then in cool goes thru the opposite side. You should have a digram present, and then on the main circuit board there is a code light. Check the light for blinking or (flash) read the bottom of the board for the code ( very small print)
well i need to know if the fan comes on at all if not then it could be a bad motor or board which is not uncommon but if the fan does come on and then flames go out and fan stays running could be high limit check to make sure in the bower compartment there are no wires disconnected from the blower sometimes when changing the filter it is possible to knock the wire off the board
I have a Rheem heat pump/airconditioner, Mod # RPFA-036JAS, that I have had problems with for at least 5 years and have paid over $1,000 in parts and service calls. I can vever recreate the problem when a tech is here. It usually happens in the middle of the night. I hear a Click, ckick, click sound, through the unit and it sounds like it is comming out of my air handler, but the outside unit also clicks at the contactor and the condensor cooling fan moter will start and stop about every half secongd or second. Both contactors have been replaced, the small one twice, one capaciter
has been replaced. I allow the unit too cool down and its alright for a few hours. That is difficult when the outside temp is below zero. HELP PLEASE!
It sounds like you have the fan turned on. If you go to the stat, you should see an auto button, or switch for the fan. If you just switch it to auto, the fan will stop, and only start when the unit calls for it, hope that helps
