Question about Goodman Heating & Cooling

Open Question

I have goodman 3AAT83D21A1 home a/c unit. Picture fell and knocked off cover of thermostat. There are four bulbs inside 2 for heat, 2 for air. How do I know if they are not adjusted now, there seams to be ( perhaps mercury balls in them). Do I need to get service? Right now air is running and seems fine.

Clicking sound is the contactor engaging to start the outside unit. Check for a burnt off wire at the contactor. For some reason you are not getting power to the outside unit. If you find a burnt off wire shut off all power to it then remake the connection at the point of the circuit break.

Hello,Good job with description.Something is keeping the condenser off(saftey).Do you have an emergency heat setting on the therm.It will run electric heat strips only until service can check it out.Very rare that the disconnect switch (black box) is it.Need electrical meter to prove it out.

My 5 ton Goodman Heat Pump won't go into heat or ac mode. Fan won't turn on. No noise from compressor. System is 1 1/2 yeras old.


Easy: Turn the "fan" switch to on at the thermostat and see if the blower starts. If no start, check breaker at breaker box. Check service disconnect at or near the air handler. With the breaker and/or service disconnect OFF check the 3 or 5 amp fuse inside the top cover in the air handler.
Not so easy: (You must know what you are doing for this part or let an HVAC Tech do it for you) Open thermostat and firmly jump the Y and R terminals to see if you get the compressor to start for no more than 30 seconds. (don't do it more than once.) Jump the G and R terminals to see if you get the blower to start. If so, u have a bad thermostat. If not, check the transformer inside the same cover in air handler for proper voltage. (24V. Make sure you also get 220 on the opposite side of the transformer)
If the blower comes on, but the heat pump doesnt start, open the side cover of the heat pump, with the thermostat on cool, and the temp. setting as low as possible for at least 10 minutes see if the contactor is pulled in. If so, check the capacitor and see if it's blown out. Be super careful these systems operate with 220v and the amperes are enough to kill you if you make a simple mistake.

Goodman AC Unit with Heat Pump - Works great cooling when switched to heat the outside unit does not come on - inside comes on and uses emergency heat? What can I check? I first checked the contactor and...


Because the outdoor unit works in cooling, it sounds as though the contactor and other components outside are working correctly. The problem sounds as though it might be somewhere in your thermostat. Has the thermostat been replaced recently? If so, make sure it was wired correctly. If not, check all of the connections and contact points in your thermostat. In order for your outdoor unit to run, you must have 24vac at your "C" Common and "Y" connections. You must have this in COOL mode. Now it has to be determined why you don't have it in HEAT mode. Definitely a thermostat issue.

Hope this helps and good luck! :-)

Units heating elements wont shut off regardless of what mode is selected on goodman units thermostat model no. ar24-1


Hi, you will need to replace this thermostat as the circuitry is faulty and keeping the strips energized. The only way to check would be to pull cover from stat and expose stat wires. Power off first. Disconnect the 24 volt hot wire, red and they should shut right off. If so get a new stat. If you need further help, please contact me. Merry Christmas.

Goodman with 2 thermostats, freezes in summer, no heat in winter


is the system zoned? if so maybe the zoning control board to the damper motor is wired improperly. when a system freezez its because of 1- restricted air flow across coil, (maybe dirty filter) or 2-low refrigerant charge. again could depend on how its zoned.
