Thermal Limiter Trip Time
Run the following test at room temperature. Set the Time Dry cycle for 30 minutes and the heat selection at
maximum setting. Place a 100% exhaust block on the exhaust pipe. The dryer door should be open for this test and
the door switch held closed. The thermal limiter should trip and shut the dryer off after 1 to 5 minutes of operation.
To enable this test, the High Limit Thermostat must be bypassed and NTC2 should be removed from the heat duct.
NOTE
This test renders the thermal limiter inoperative, a new thermal limiter must be installed after this test.
