Minim 20 amp circuit ... is this 110 or 220? You need to know.

20 amp circuit needs to have #12 wire. If 110 Volts, you need a black, white and green #12. If 220 Volts you need a black, a red, and a green. If you have anything IN the unit that needs 110 (probably not), you need black, Red, White and Green (bare) #12 wire. Definitely needs to be on a dedicated circuit. If your unit has a resistance heater (electric) you will need a 30 amp circuit (probably 220) which needs #10 wire minimum. 220 volt breakers are double. You will need two spaces in your panel box. Would not hurt to put in heavier wire (#8) protected by a 30 amp breaker ... $ is the governing factor.

Having said all of that --- you should be reminded that I dont even know what country you are in nor your prevailing voltage nor what your national or local codes require. My comments based on installing several Goodman products over several years on the Eastern Seaboard.

I ASSUME YOU MEAN TO FEED FROM PANEL THE ANSWER IS YOU MUST RUN 2 CIRCUITS OF 3-cond #6 copper to unit connect the feeds to one breaker and the other circuit to the other breaker the neutrals connect to lug provided or purchase them and frame gnd to case , i would not recommend anything except copper as most mfg do not rec aluminum because on the heating and cooling of the unit and conductors

SOURCE: Goodman PC060-1B Package AC...Need Wiring Help

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

Sounds like the heat pump is not running. Check outside to see if the fan is spinning.

Try moving the thermostat to emergency heat and see if that gives you any heat. If it does, then you have heat until you can get a service technician to locate the problem with the heat pump. It could be a wide range if issues from bad thermostat to bad wiring to bad capacitor.

Goodman package unit heat strips will not turn on


Put meter probes at in put terminal of the element if you read 220volts that mean your relay is good. if you got it there use amp meter on one leg of that element. You should read some amp draw there but if there is no amp draw it mean the element broke.

Goodman PCK-060-1C. suction 52, coil/filter/blower/restrictor/drier okay. Recovered the charge and recharged with factory specified amount. The return air 1800 cfm. Motor 3/4 hp. It seems to me the motor...


It seems to me that your suction should be @ 76 or so. 52 is low. the coil will ice up with any suction PSI below 58. Disconnect the unit from the duct work and make sure there is no restriction in the duct size. In other words. Does the unit work properly with out the duct? I find most mobil homes have a restriction in the amount of return. A 5 ton split needs a 20 inch round return. You never see this size return on a package unit. Does the return **** the filter in? I have had to add returns to large mobil homes because there just not designed right.
this is only a possibility. Is the temperature split on the equipment between 18 and 20 If it is then I don't thing you have an equipment problem. Also make sure there are no holes in the duct work.Last one I had unit was working fine but the duct work had a big hole in it from some animal under the trailer.
