I have a Kenmore (Goodman) heat pump unit 7 years old. Approx. 2 years ago Sears changed some sequensors and I have had problems since. First of all they cut plugs off original wire harnesses, why I do not know. But now on heat mode when thermostat set at certain room temperature furnace will run and keep rinning forever after reaching set temperature unless I set thermostat down 2 or 3 detgrees manually. Also while running to reach set temperature it will sometimes drop 4 or 5 degrees befor reaching set themostat temp. Sears has looke at, but since they created this problem seem to be lost in reolving it. What is causing this problem?

FIRST i would use a multi meter and check elements for power. one or more may not be working. SECOND iwould check sequenser . also look for burnt wires at element and throughout. probably sequensor they are usually under 20 dollars. the wires on very bottom of sequensor should have 24 volts when heat is on.
Yes, if you are talking about a heat pump. It you have an electric furnace inside, the electric elements are for emergency heat. Otherwise, unless you switch it manually at the thermostat, the heatpump (outdoor unit) will run all year around. If you want to use your inside heater (electric heater) just switch your thermostat to "emergency heat" and it will turn on the electrical elements instead of the outdoor unit. This way will make your elec. bill higher tho. The heat pump is much more efficient. Hope this helps you , have good day
If you have a AC unit with electric or gas its doing what its supposed to do, let the pressures in the system equilize before starting again, If you have a heat pump its doing it there as well you just have not noticed. Anti cycling is a good thing, 4 to 5 minutes is normal.
Hi, You are right. The outside unit starts quickly. The humming will either be the evaporator fan or the AC compressor itself. If you can reach into the evaporater fan with something narrow and stiff you may be able to see if the fan turns. Sorry for the trouble you are having. One or the other is trying but unable to start, hence the humming. Wayne
That does not sound normal at all, I have a Goodman Heatpump and the Fan on the Evaporator (outside unit) should run as soon as it starts up! The only delay you should be seeing is when the unit starts, the fan in the AHU starts 5 seconds after and runs for about 1.5 minutes after shutdown.
Depending on the size of your Electric heat you can use one set of wires because your unit does not run with the heat like the heat pump. The large set of wires going to the electric heat should be used. You may have to jumper a new set to the contactor. On Goodman unit come in L1 and L2 jumper to contactor. Very simple good luck. Rus
Do you have a heat pump? If so this is normal. You are probably used to a gas furnace. There are heat pumps that do have a delay though. Look on the circuit board in the air handler. There may be a set of pins that say 0-30-60-90 yours may be at 0. Also some digital T-stats offer that function for delay off to get the extra heat or cold from the system. Find out what the model number of the air handler and call the Goodman supplier in your area to see if you have these options. If you have a gas furnace and it's not delaying the blower there is definately something wrong.
I would insist that Sears either have a Senior tech come out and fix it or return it to the state it was prior to them touching. Then call some one else. Have them involve the Goodman rep in your area.
