There is a gas valve that controls the burner and has a flame sensor that keeps it from supplying gas when there's no flame. There's a chance that the unit overheated and caused a heat overload protector to fail, which was a safety feature to keep the unit from becoming dangerous. You may need to replace that overload protector. The pilot light may have just went out, and you'll need to light it again and make sure the gas valve is set to on. The flame sensor may be dirty and thinking the pilot is not on. The flame sensor will be a wire or probe mounted close to the pilot light. The gas valve may have failed and need to be replaced. You probably can't cause a lot of damage by just looking around in there and cleaning the flame sensor, but you're dealing with fire here, and you should leave anything like taking the gas line apart to a professional.

How do you check a fan motor

You need to check the volts at the motor while it's running, to make sure some safety is not shutting it off. Then check the amps on the motor while it's running. Also you need to check your capacitor and wiring.

Stops after 4 mins

Can you hear the "whirl" of the fan? It is possible the fan is not turning & cooling the oven therefore it will shut down when it reaches a certain temperature. This could be caused by a supply fault to the fan or the fan motor, either way it would need to be tested by a qulified engineer.

Car fan won't turn off

Is it over heated? It is normal for an overheated vehicle to keep the fans on to cool down for a little while. If they dont shut down after a few mins, then check the wiring for any shortage.
I hope this helps!

Amana Cooling Condensing Unit fan stops spinning after 15 mins

Capacitor, dirty condencer coil causing the motor amps to run too high. But most likely worn bearing on blade side of motor causing it to pull to one side causing it to over heat and shut down. Sleve bearings should have no side play.

Projectors keeps shutting down after 20 - 30 seconds

reason for fan spinning at high speed after shutdown is to cool down the projector after it has been on
you will feel hot air from exhaust as this is taking the heat away from the lamp, where all the heat is generated
if it shuts down after 20 mins either the projector is blocked, maybe, a fan is not running, filter blocked, or the motherboard is now u/s

New 95% goodman keeps giving Code 1

Not having a model number to help you with, I can only give you generic info. Typically a flashing 1 represents that the furnace has exceeded its allowed attempts to start. Not much help. If I can suggest removing the access panel on the furnace and tape down the door safety switch. That being done, have a helper turn up the thermostat and you get your head inside the furnace cabinet and document what it does. It should first blink on the LED indicating a call for heat. Next the inducer blower should start up (the small blower hooked to the exhaust pipe). Next you may see an orange glow where the burner is. There should be a small clear port where you can watch this. Next some clicking should be heard from the gas valve. Then the orange glow should turn to a blue flame. This flame should travel all the way right and left igniting all the burners. Then it should stay on until the call for heat is satisfied.

After doing this and with your model number, get back to us and we may be able to pin-point your issue.

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?
