This is tony my thermal fuse is kicking off every 15 min what would cause this problem ?

Door Switch Start Your Repair Here

- Takes less than 15 mins
We have 13 installation instructionsThere are many reasons your microwave won't turn on, one of which might be a faulty door switch. The door switch, also known as an interlock switch, signals other microwave components to begin powering when the door is closed, and to stop when the door opens. For this reason, everything else may appear in working order but the microwave will not begin heating. To access the door switch or interlock switch, unplug the microwave and dismantle the cabinet. The switches have terminals which are marked C for common and NO for normally open. Check each terminal with a multi-meter for continuity. If there is continuity while the actuator button is engaged, that means the switch is working. If there is no continuity, replace the switch. You can also take this opportunity to make sure the door hooks are working properly.
Ceramic Fuse Start Your Repair Here

We have 1 installation instructionIf your microwave won't start and the display is blank and unresponsive, the issue may be with the ceramic fuse. This part protects other microwave components from power fluctuations, and causes a complete loss of power when it fails, meaning your microwave won't work. To access the ceramic fuse, located inside the cabinet near the power cord, first unplug your microwave. Use a multi-meter to test the continuity of the fuse. If you are aware of the cause of the fuse failure, such as opening or closing the microwave door, you can also test the door switch to see if that is working. If you are unaware of the reason for the fuse failure, you may want to test other microwave parts such as the magnetron, high voltage diode, capacitor, and transformer.
Thermal Fuse or Cut Out Start Your Repair Here

- Takes less than 15 minsA problem with the thermal fuse or cut out could be the reason your microwave won't turn on. The thermal cut-outs, also known as thermal fuses, help keep the oven from overheating. When the thermal cut-outs fail, your microwave won't turn on as a safety precaution to keep it from getting too hot. To access the thermal cut-outs, first unplug your microwave and then remove the cabinet. Once you locate the thermal fuse, disconnect its wires from the terminals. Use a multi-meter to test for continuity, and replace the thermal cut-outs if there is no continuity. Take this opportunity to also check that the cooling fan is working and not causing the microwave to overheat by cutting off airflow.
Door Latch Assembly Start Your Repair Here

- Takes less than 15 mins
We have 4 installation instructionsYour microwave may not start because of an issue with the door latch assembly. Most door latch assemblies are made of plastic hooks that stick out of the door and engage the door switch when the door is closed, signalling the rest of the controls to power the microwave. If the hooks are damaged or lacking tension due to worn-out springs, the switch will not latch properly meaning the microwave won't turn on. To access the door latch, first disconnect the microwave from its power source, and remove the inside door panel, which is held in place with plastic tangs. Inspect the door latch and replace it if it appears to be damaged.

Any possibility there's a problem with an obstructed vent?

Hello,
Your gonna look for the drivers side fuse panel on the drivers side (kick plate). Remove the screw and the pull off the access panel. The fuse you need are fuse 2 which needs to be 15 Amp and also 6 also a 15 Amp See diagram -

The moister sensor can be bad or good. If the exhaust tubes are clogged with any lint build upo the sensor is working putting the burner into check

Sounds as if the thermistor has gone bad. This sets down on the blower housing next to the thermal fuse. The thermistor assembly is a part number 1268206 from repairclinic.com at about 15.00 Good luck and hope this helps. Rick

Sounds like the thermal cut-off is kicking in. Try checking the vent to make sure its not blocked and causing it to overheat, this would cause the cool down (the other candidate is a bad fuse, but if you fixed that already I would leave that for last)

Blown fuse?

Cause 1Thermal Fuse
The thermal fuse is a safety device designed to protect the dryer from overheating. The fuse is located on the blower housing or at the dryer's heat source such as the heating element on electric dryers or at the burner on gas models. The fuse should be closed for continuity meaning it has a continuous electrical path through it when good. If overheated the fuse will have no continuity meaning the electrical path is broken and the fuse has blown. A multimeter can be used to test it for continuity. Be aware that a blown thermal fuse is an indication of a restricted exhaust vent from the dryer to the outside. Always check the dryer venting when replacing a blown thermal fuse.
Parts Cause 2Gas Valve Solenoid
Gas dryers have two or more gas valve solenoid coils. The gas valve solenoids open the gas valve ports to allow gas to flow into the burner assembly. If a gas valve solenoid fails, the dryer won't heat. To determine if one or more of the gas valve solenoids has failed, check the igniter. If the igniter glows and goes out but does not ignite the gas, the gas valve solenoid is defective. If one or more of the gas valve coils are defective, we recommend that you replace them as a set.
Parts Cause 3Igniter
The igniter uses heat to ignite the gas in the burner assembly. If the igniter is not working, the gas will not ignite, preventing the dryer from heating. To determine if the igniter has burned out, use a multimeter to test the igniter for continuity. If the igniter does not have continuity, replace it.

Hey,

Buy high quality batterys.

Thanks,

It is probably either the high pressure switch or the frost control. The high temp switch usually trips because the condenser coil is dirty which does not allow it to exhaust heat very well. The frost control will trip if the system gets below 39 degrees on the pipes. This is usually do to low refrigerant or dirty filters. Good Luck!
