What would cause the high limit thermostat to keep knocking off and have to be reset?
Answer Hello Adam. You need to check the venting of the unit. If it is clear and is not kinked, you will need to replace the thermostat 00170857. It has become weak and is tripping.
What is that red button for? My dryer heater does not work and that button cannot be pushed in or pulled out.
Answer Hello Ron. The button is a rest for the thermostat. If the thermostat is open and will not reset, you will need to replace the thermostat 00170857. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter.
