Goodman gmp150-5 Three blinks of trouble code

the problem sounds like it is with your combustion fan motor,,,there are two types. one has a syntrifical swith the others have a round box with a hose going to it that is a pressure switch, if it is the motor does not have a rubber hose coming off and has two wires instead than that is syntrifical and your only shot would be to take the moter loose and shake it out make sure there is not something that fell down in and kept it from turning, other wise u have to replace. by the way it will be the small motor at the base of the vent pipe. If it is the hose type try unplugging the two wires from the little round box that the hose goes to and connect them together if it runs by bypassing that then either the switch is out or something is plugging the hole or hose,,on the side of the blower moter where the hose comes out try poking something through the hole and make sure it is not clogged I bet this is the kind u have and the problem. good luck

Goodman furnace model #capf030b2c 4 blink code blower runs constant but no heat

https://hvac-boss.com/troubleshooting/goodman-furnace-error-codes/ According to this page, you can usually fix this 4 blink diagnosed problem by changing the air filter or tightening wiring (which it has a cautionary warning about tightening such too much) and checking the flue for blockage. The furnace has activated the primary open limit circuit. Here is a troubleshooting page about the Goodman just blowing cold air: https://temperaturemaster.com/goodman-furnace-troubleshooting/#Goodman_Furnace_Blowing_Cold_Air Poor air flow in the Goodman caused by blockages can result in the tripping of the rollover switches which would cause it to blow cold air. That is a safety measure. You don't want gas furnaces burning with insufficient air. Think carbon monoxide. Besides the air filter, the flame sensor or the burner could be dirty. The idea of trying to DYI that cleaning job is rather off putting. I hope changing the filter would work. I trust it is not a fuse in the pilot flame sensor circuit blown. A repairman has the voltage testers for checking the electronics involved. I can empathize with this. My furnace, another brand, went out recently. The repair man didn't know why it went out but simply adjusted a handle controlling gas flow to a position slightly different from what was recommended and it worked. All for $200. https://www.repairclinic.com/RepairHelp/Furnace-Repair/36-377--/Goodman-Furnace-Troubleshooting https://www.youtube.com/watch?v=zO1jKqwXu8s https://www.goodmanmfg.com/products/gas-furnaces

Goodman furnace blowing cold air. The blower is working. No flame at all, look at red light, no code.

Power it off for 5 minutes, and then power it back on. Some ideas in the link. https://www.google.com/search?q=Goodman+furnace+blowing+cold+air ..

Goodman gas furnace model number gms80904bna won't light. Changed the flame sensor and the ignitor is bright orange please help

Obvious that the unit isn't getting gas to the ignitor. To receive gas to the ignitor, there is a gas valve located upstream of the burners. Have a friend turn on the heat while you are up close to the furnace. Once the ignitor gets hot, there will be an audible "click" at the gas valve when the low voltage controls call for the gas valve to open to supply gas to the burners. Listen for it. If you hear a click, and the furnace still isn't firing, you need to check to see if someone has closed the gas shut off supply valves located on the gas line. If all the shut off valves are open, you need to verify you have gas pressure in front of the gas regulator. If you verify have pressure on the upstream side of the regulator, you will need to verify there is also pressure downstream of the regulator. If there is gas pressure upstream but none downstream, replace the regulator. If you have pressure downstream of the regulator, and the gas valve clicks, but furnace doesn't light, replace the gas valve. LP has higher pressure than natural gas, and is dangerous. LP is heavier than air and will sink to the floor or lowest area. One static electricity spark is all it takes and an explosion can occur.

Goodman furnace not heating, low fire pressure switch stuck open.

Question edited for typos.Gas furnaces has safety features to prevent explosions. If anything is thought to be faulty, nothing works. All gas appliances must be repaired by a registered gas technician. The two pressure switches are $76 and $29 if you want to risk it.https://www.goodmanparts.net/category/goodman-gmv950905dxa-gas-furnace-oem-repair-partsThere is videos and help here.

GMS80903BNA goodman furnace. Short cycling

I have the same problem. The vent flu. Is building up condensation and running back into the furnace and cloggs the little black vent hose with water. Then it comes back on then off etc. somehow the trick is to make as straight of an upward vent flu as possible ( definitely not 45 degree elbows and really not 60's either) seal all connections with glue.
