You have either a misadjusted fan switch or a bad fan relay. Or your thermostat has a fan switch on it that may be in the "On" position. Check the thermostat first, then if that is not the case, you will need to call your technician.

No heat from furnace, Goodman GMPN080-4 Rev A. Cycle is solid red status light, then 3 flashes indicating open pressure switch because the inducer fan does not come on.


Jimbo, it sounds like you are aware of the operational sequence to suggest using a voltmeter to check the actual wires going TO the combustion air fan...if there is no voltage from the board, the board is bad. Just make sure one of the high temp limits are not open... one may be in the blower compartment on some and one will be near the top of the vestibule and a roll out switch should be near the burners. They should all be wired in series.

Always check the manual reset safty switches as the first step in troubleshooting.

After one heat cycle, the blower motor keeps running, even after cool down is complete. The furnace will not refire until i turn off the power and wait about 20 minutes for a reset.


your limit switch is opening up, that causes constant fan. Check for flashing codes after flame shuts off and fan continues. Check airflow, filters, lack on return air for possible hi temp limit problems.

you could try check the AFC automatic fan control which brings the fan on temp rise and shuts off on temp fall, see if its clean on the back of it, check filters are clean try cleaning flame sencor , the afc inside the cover the temp dail turns back when cooling see if this sticking none of this will cost you, just time.

My goodman furnacs says my limit switch is bad blower works but does not ignite .....? its modle gmt070-3 and where is it located


There are several limit switches in the unit there in various places in burner compartment. One on blower housing . One thing that I would try is replaceing your filter and turn the power off to the furnace and try starting the system after power is D/C for 5 minutes.

Heat pump fan does not always turn on when heat pumd does. Is this a fan relay problem? If so, is this something a homeowner can replace?


if you are talking about the indoor fan on the unit and it is a electric heater then yes there is a fan relay that control the fan operation that is common to fail on these units.. it is fairly easy to replace and can be purchased on line at diiferent heating sites... type in goodman heating parts in a search engine and locate the relay you need... if you are talking about the outdoor fan motor then need to check a few things there is a capacitor that helps motor start that could be weak /by the way there is also a capacitor on the indoor unit you want to check to .... it usually is 5-20 microfarads that requires a meter or tester that can check the farads on capacitor... make sure these are good... the outside unit will sometimes not have the fan motor run if the unit is in a defrost cycle but should only stay of for 5-15 minutes at a time and only if it is in a defrost cycle ... hope this helps you out repost if you have anymore questions...

My honeywell Thermostat reaches the heating temp. but the fan will not stop running.And yes the fan is set to auto.It just keeps running and running and running.It stays the same temp but will not shut off...


I want to give a simple explanation before I go any further. On the heating side of a unit even though tthe temp has satisfied the thermostat, the fan will run until it cools down the plenum where the air flows from the air handler. There is a bimetal switch called a fan limit that operates the blower when the plenum reaches the temp set on the fan limit switch. Now if your fan keeps running even after the plenum chamber has cooled down, then you could have a fan limit switch that is stuck in the run position and must be replaced in order to correct the problem.

My goodman furnace model gms95 has gone ape. when the thermostate calls for heat, the furnace kicks on and starts to cycle but it wont stay on long enough to reach the set temp, before it kicks off. and it...


It sounds like your furnace is cycling off because your high temperature limit is tripping. This could be caused by a restriction of intake or outlet airflow. First thing to check is your intake air filter, clean or replace as needed. If that doesn't help, make sure your warm air registers are open, a rule of thumb is at least 60% of the total registers need to be open for adequate airflow. The high temp limits will reset themselves after they cool so that would explain it taking a few "cycles" to reach desired temperature. Good luck and please rate my answer if it was helpful.

No heat, trouble shooting light has continious flash.


There is a vacuum sensor on most units tied from the exhaust gas fan to the sensor. Does the unit try to start? If the unit's exhaust fails to pull the switch it will turn off after about 30-45 sec after starting. "IT" thinks it's not exhausting and stops to keep from overheating. Do you have this exhaust fan and rubber hose to sensor? Can you see if that fan is turning on start?
