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 just installed this unit and can not get the blower to run


Seriously depends on what unit you have. Model # & serial #? You can "jump" R to G at the unit. If its a standard Goodman AHU there may be a terminal block or just some wires that were factory installed outside of the unit. R to G will send 24v to the blower relay, sequencer or board (depending on model) energizing the relay and then returning to common. If you have tried that you should ensure you have proper line voltage 220-240vac. at the service breakers on the AHU.

Continuing running, Ice on outside unit


Every unit has to take rest to re boost. That's why thermostat for heat or cold fixed, If your unit is not cutting off @ setting temp check room sensor. If defective replace it.
If unit continuously running but no cool inside room means gas leak. Find leak and do gas charging.

Installing 1 1/2 ton Weatherking Heatpump and ADP WAK351807P2 air handler 1 /1/2 with 7.5KW back up heat kit. Can't seem to get the thermostat hooked correctly. I understand the Weather King product...


O energizes the reversing valve when the thermostat is set for COOL. B energizes the reversing valve when the thermostat is set for HEAT.
The O/B is usually a orange or black wire.
You can't hurt anything if you choose O or B incorrectly. Hook one of them up and run the unit. If set for COOL and the unit runs cool inside it is correct. If set for COOL and the unit runs warm inside it is not correct.
If the inside temp is opposite from your setting change the wire to the other terminal.
Remember to disconnect power from the air handler when changing thermostat wires.
The defrost control board on the outside unit should be marked correctly for O or B.
Your thermostat may have a slide switch rather than a separate terminal.

Furnace runs on heat, air conditioner does not


If you have a Gas furnace in the Attic then the answer is yes. The outside condenser will not run if in fact you have a gas furnace.

Weather King Heat Pump


Hey kellyrepp -- Three things to check quickly, so many things can be wrong, but i will try to help with the info you gave me.

The first sounds like your electric aux heat is not wired in or not working correctly , this should kick in when the heat pump cannot keep up with desired set temperature. For sure thats a problem

The second thing i would check is that the compressor for that unit is running. It should sound exactly like the one for the upstairs, the fan noise should be like a whrrrr , and the compressor should be a semi loud hummm.

Third feel the pipes on the outside unit that are on the outside of the unit (the unit for the second floor) Let the unit run for 5 minuites. Now check that the first floor unit pipes are the same tempereture. They are about 110 degrees or so, depending on the outside temperatur , be carefull not to burn yourself. If the lower unit is colder , the two most prominent problems would be #1 the compressor is not running #2 Low on freon.

Hope that helps

I'm trying to figure out if our Weather King system has a heat pump... how do I tell?


Your indoor furnace is weather king? If you have a a/c unit outside, it could be a heat pump, but you have to provide the model number on it.. If you do have a unit outside, when you call for heat does the outdoor unit kick on?

Heat strip install


What color wire is connected to the "Y" terminal on the thermostat.
If the unit you are connecting is a heat pump A/C unit the orange wire is for the heating mode. Normally the "Y" terminal on the thermostat. "R" terminal on the thermostat is the power to the thermostat, "W" terminal is for heating, "Y" is for cooling, and "G" terminal is for fan operation. At the condensing unit for cooling the brown and yellow wires would normally be for the cooling.

Fan not blowing


Even when the power is off at the unit outside the thermostat will supply power to the contactor of the outside unit. This may give a hum or buzz as you stated. If when the power is on to the outside unit the fan tries to start but only hums the motor may be bad. Does the compressor start and run?
