There is a sensor that senses if the heater has an adequate VENT like an oxygen sensor on a car, if that has gone bad the heater will think the blower is not blowing and shut everything down to avoid building up gases in the home.Also check the tube that vents to the outside.If it is clogged the same problem will occur.I am no expert but when my heater went out last year I was forced to learn the ins and outs of heaters.HOPE THIS HELPS.

AC fan blows less air after extended use

Sounds to me the blower motor is on it's way out and should be replaced. Even though they sound like there working doesn't mean everything is ok with it there are different parts on it that could go wrong and they way to fix it is with another blower fan and not a bad idea to do the resistor at the same time located in the blower box with about 4 wires coming out of it with one or two screws holding it in place all is located under dash behind the glove box area.

Have a gmp125-4 furance blower runs all the time checked themostat wires error code 1 blink then 2 then 3 then 5 furance works if you turn power off turn back on when heat kickes off blower comes on gives...

Sounds like limit switch issue. Furnace heats up, high temp limit switch opens, fan will stay on. GMP model is older and do not have the codes.
May be over fired, have airflow problem, to cause the limit to open.
Next time before shutting off power, try to find the limit, it has two wires that connect to a 1.5 x 2 inch card mount to the furnace fire wall. tap on it and see if the blower stops. If so replace the limit.

Furnace blower blows cold air

It is possible that you did not set the new blower on the proper speed. Black wire is high. Blue is medium. Red is low. If the fan is operating to slow it can run to hot and trip the high limit control. Make sure the filters are clean. When the old motor went bad, the problem might not have been discovered rite away your high limit control might need to be changed.
Also anytime you work on a furnace you can kick up some dust. Always clean the flame sensor.
Good Luck

2005 jeep grand cherokee 4.7 Ac fan lost the 3 lower settings, only the high setting still worked. For a while the lower fan settings would just come on, and then go out again. The high fan setting...

Well, the blower resistor handles the lower speeds and the hi-blower relay handles the hi speed only. if the fan still works on the lower speeds then the resistor is bad. if the fan doesn't work at all then your motor has failed and or burn't the relay out also. if you can get your blower to start by hitting the kick panel above the pass. side foot area then the motor is bad. if you are handy enough to drop the kick panel and access the motor then check the connections at the motor. Then wack the motor and see if it comes on then. you will most likely find the problem if you follow those simple rules above. Good luck.
