Electrical Tests For Electric Dryers Only
High Limit Thermostat Cycle Time
Trip:
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 by tape or similar means. The thermostat must open (heater off) between 35 to 120
seconds.
Reset :
When the exhaust block is removed and the door closed (keep tape over door switch), the thermostat must reset
(heat on) within 120 seconds.
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 off the heaters 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.
Drum Temperatures
The following tests should be run with an unrestricted exhaust. The location of the thermal couple is to be the square
in the lint grill which is 12 squares left from the right edge of the lint blade and (2) squares forward. The tip should
extend 1.25” into the air grill. Set the dryer timer as needed for each test. The recordable temperature is to be the
maximum temperature following the heater off of the 3rd cycle.
No load is to be used for the following heat settings:
Heat Setting
Thermistor Status
Temperature (°F)
Max*
Satisfied/Heater Off
120 to 160
Medium*
Satisfied/Heater Off
110 to 140
Low*
Satisfied/Heater Off
95 to 130
* Each opening temperature should be equal to or higher than the opening temperature for the next lower
temperature setting.
This test renders the thermal limiter inoperative, a new thermal limiter must be installed after this test.
