Question about Heating & Cooling
The outside Tempstar unit is about 7 years old. It was installed to replace a failed unit and some modifications were made to match the Tempstar to the inside air handler system. I was told the outside unit is shot though I could not get a repair cost (or what was shot). I was told the "old" air handler/heat unit is so old that I probably could not find the 4 heat elements that have burned out. The home was built in 1996 so I have no idea that this would make the exchange unit too old. I hate to even add that my wife overheard the guy when he called in to his office and told "whomever" that they had a sure sale on a replacement system. Anyway we used our gas fireplace heat for the remainder of the winter and now it is too warm to without getting a solution for the hotter weather.

SOURCE: Air Conditioner malfunction
Hi, Sounds like you have a short in the control circuit to me. Turn off all power going to the unit. Write down or otherwise mark the wires leaving the control board going to the thermostat. Remove them from the control board. Replace the fuse. Turn power back on and see if the fan still runs. If it does, check and or replace the heat limit switch that brings the fan on during the heat cycle. It may just need adjusted. If the fuse blows, I would think that the control board is probably bad. If it doesn't blow, Remove the thermostat. Leaving all thermostat wires open check them with an Ohm meter. There should be no continuity between them. Twist all the wires together at one end and ohm them again at the other end. You should have complete continuity on all wires. If the wiring checks out, down power the unit. Double check your wire colors and rewire the control board. With all wires open at the thermostat, turn the power back on. Touch the RED wire to the YELLOW wire. The Condensing unit should come on. Touch the RED wire to the GREEN wire. The fan should come on. Touch the RED wire to the WHITE wire. The heat should come on. Down power the unit. Replace the thermostat. Test unit. If the fuse has lasted ok but blows now it is either wired wrong at the Thermostat or the thermostat is bad. I hope I have helped. NOTE: If you can not understand these instructions. Call a licensed Heating / Air conditioning company. kstfas

It sounds like you might have a short in the wiring that goes from the furnace (inside part) to the condenser (outside part). Follow these lines by hand and check to see the wire isn't damaged and shorting out.

I recommend getting electric back up heat to fix your problem. Like the other gentleman said, defrost is having to kick on too much. It's doing the best it can givin the conditions outside. If you don't have enough power supply for electric back up heat, then a gas furnace or propane furnace will work also, depending on your needs. Heat Pumps are a like a full time fan, they are designed to heat your home at a steady rate unlike forced gas units that turn on extremely high temps and then shut off... Ensure your charge is correct, givin your tempatures the unit sounds to be working correctly, however a second opinion is always a good piece of mind before you spend money on emergency heat.. Hope that helps..
