Question about Goodman GMS90703BXA Heater

Goodman air handler

I am a service tech and trying to help out a friend. He said his a/c is not working. Found the unit is completely out of freon. The leak was on one of the distributor tubes that go from the back side of the metering device to the indoor coil. I replaced the indoor coil and weighed in the charge. My head pressure is now running 150psi and suction pressure is going into a vacumm. In the heat mode the high side goes to 250 psi and suction is around 45psi. I am thinking I have a blockage but cannot figure out where. I checked to insure the new metering device that came with the new coil was the same size. can you give me some more ideas on what to check next.

A thermo-laser reader will let you know if, and where you may have a resrtiction by giving abnormal, or various temp. readings. Make sure that your filter line drier is good as well. If the drier has not been replaced, i would suggest that first.

Where is the filter located?

Hi, if this is a central system that is split up with the condenser outdoors and the air handler indoors it can be in the indoor unit it self or also it may be in the ceiling or wall near the unit behind a grill for the return air to flow back. Walk around and look for this grill. It is either up high near the air handler close to it, or low on a wall near it. If not out in the home, you will find it in the indoor unit only, nothing outdoors. If you remove a panel you should find it. Please keep me posted and please don't forget to rate me as I no you will be kind. I will check in on you a little later to see if you have found it.

Are these still under warranty

Hi, the only part on your unit that they will put a warranty on when it is new is the compressor for 1 year only. You can buy an extended warranty on the compressor for 4 years. If you loose a part now, and have to call out a tech to replace it, they will give you a 6 month warranty on parts alone. Doesn't seem right, but that's the way its done. Some contractors try and not give you any!! That's wrong and will come back on them. I hope I have been of help to you on this when you rate me. I know you will be kind.

Thermostat not connected for Multi-Stage Furnace.

You need to get a service tech to hook it up for you and yes you need to take advantage of the two speed furnace and varispeed air handler. If it is set up correctly you will be more cpmfortable and will have amuch lower energy bills. Tey are not hard to wire but you have to know what you are doing to do it right. So call Goodman service tech out. Amana is the same product so either one. Should not cost very much and it will pay for the service call in a couple of monthe. Rus

My goodman air handle is run on e-heat only and will not turn off ,also the outside unit will not turn on , I put a new themostat this didn't help I have a goodman heatpump

Heat-Pumps can be temper mental. Sounds to me like your air handler is running on emergency heat, due to a problem with the condensing unit.You have heat strips in the air handler in case the outdoor temp. gets to cold and the heat pump cant keep you're home warm.Also, if you loose a compressor, it will go into emergency heat. If you have lost the compressor for one reason or another, lets say a locked rotor, the compressor would draw L.R.A. (Locked rotor amps) and cause the circuit breaker to trip. Check this.As for the air handler running all the time, you said you replaced the stat? When you removed the control wiring from the stat, did the fan shut off? I wish I were on site to help you, but all I can do is offer you some advice. With the power off to the air handler, go to the stat and remove the red and green wires. Turn power back on and see if it stops running. If it stops, then it sounds like the new stat is also faulty? If it continues to run, check the wiring in the air handler to make sure the red and green are not touching somewhere, and also check the control wiring on the outdoor unit for the same problem. Do you have any dogs that may have chewed into wiring? If so, check all outdoor t-stat wiring. There are so many things it could be and I hope very much I have helped you with solving this online, which can be difficult. You may also have a faulty defrost board. Try to do what I have asked of you.
Good Luck, Sincerely, shastalaker7

Central air unit two part system, inside and outside. Freezes

If coils are clean and blower is working properly,
then you're probably low on freon.

Service manual for Goodman Heater # PGB036100-1

sounds like that model # is for the A/C coil or its a heat pump air handler. In any event I am not aware of any "repair manual" that is put out by Goodman to the public. They have classes on their equipment but they are geared to the professional serviceman.

If you would like to descrobe the problem, I will try to help you.

Ever hear of this odd problem?

Sounds like the main circuit board. Get the freon level up to spec and if you can live for now with the inducer fan issue, let it ride. It will fail at some point.
