Question about Goodman Heating & Cooling

1 Answer

I have a Goodman AR36-1 air handler. when I turn on the AC or the heat the air handler motor comes on for about a minute or two and then shuts off. The heat pump continues running and I can hear the air handler switching trying to turn on every few minutes or so. I put my hand on the motor and it is definitely hot. If I shut off the circuit breaker and let the motor cool down and then turn it back on, the motor kicks in and then shuts down again after a few minutes. So, the motor is good but some sort of solenoid or something is bad. What is it that I should test or just go out and buy to replace & install? I need an answer ASAP, as cold weather has kicked in and it will drop[ to 38 degrees tonight. Thanks to whomever can help me with this.

10 year old Goodman central AC won't come on after mini power outage. Breakers and wall thermostat OK.


Check the start capacitor for proper value and replace if necessary.
Ditto for thermostat. There are also some fuses in the air handler that might need replacement.

You may have had a power surge that had a bad effect on electronics of unit. Make sure that unit is receiving power for one thing. U might try to reset the electronics by completely shutting off all the breakers to compressor and air handler and waiting a few minutes and then reconnecting.

What cause 3 amp fuse to keep blowing when power in turn on goodman air handler


The 3 amp fuse is in the red low voltage (24 volt) thermostat wire
and only gets power when the thermostat is set to turn on heat or a/c It should be connected to the red wire from the thermostat

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.

Air handler running but nothing coming out of


Shut unit off, remove door that would have the blower
located in it. Make sure that the blower motor has not seized up. Try to spin it with your hand.

If the unit starts up ,fires up and shuts down all the time, more than likely the blower motor is the problem

WHEN THE HEATER COMES ON THE FAN STARTS INSTANTLY AND BLOWS COLD


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.

Air handler only blows air for 3-5 minutes before shut off & not cycling frequently


Sounds like it could be a very weak run capacitor on the blower motor. Run capacitors are sized specifically to the needs of the motor. When a run cap gets weak, the motor trys to compensate for it by drawing more power. More power draw = more heat in the motor, then the motor will overheat and shut off to protect itself. When the motor cools off it will automatically restart and run until it overheats again. Keep in mind that I am a technician that normally diagnoses equipment in a hands on manner. There are many practices and concepts that transcend all air conditioning systems but it is a constantly evolving industry. I live in south eastern WA and I don't see Amana units except as window units. It is possible to have something else causing this problem (faulty thermostat, failing thermal relay(if used), problem with electronic controls(if used)) there are a lot of potential variables
