1) Shown are the steps below to test a thermostat using a multimeter. Please note that this test will test for continuity (resistance) of the thermostat and not for voltage. This is the standard test for testing a T-Stat.
A) Unplug your dryer or turn off power source to avoid risk of electrical shock.
B) Remove the thermostat from the dryer.
C) Set your multimeter to the lowest setting for Ohms of resistance. When using an analog multimeter, calibrate the meter by holding the probes together while adjusting the needle to read 0 (zero).
D) Touch one meter probe to one thermostat terminal, while you touch the other probe to the other terminal.
E) If the multimeter shows a reading of 0 (zero) ohms of resistance, then the thermostat is good.
F) If there is little or no change in the multimeter resistance reading, then the thermostat is defective and needs to be replaced.
