Customer Questions and Answers for Dryer High-Limit Thermostat by Frigidaire

Hello Chris, The thermostat will not cause the circuit breaker to trip unless it is shorted to ground. Normally a thermostat will just go open, which will not trip a breaker. I would first check the terminal block, (where the pigtail cord connects to the unit), and your receptacle. If the unit is heating at all, the thermostats and heating element are fine. The problem may be in your exhaust duct. Many people will argue about this but if the duct is too long, restricted, or crimped off, it's the same as stopping up the exhaust. You see, the issue with this is the fact that if the exhaust can't exit the appliance, it will simply blow past the felt drum seals and re-enter the cabinet where it will trip the thermostats off, put a layer of lint on everything in there, and cause a premature failure. Let us know if we can assist further.
