Simulated
Resistive device
Step1. Position powerswitch on gas control to the
“OFF” position.
Step 2.Disconnectsimulated resistive device from
gas control.
Step3. Using a multi-metersetto the ohmssetting
check resistance of simul
ated resistive
device.Resistance must be within 25,000
ohms and 45,000 ohms.Ifoutside of this
range replace the simulated resistive device.
If there is no continuity test the resettabl
e
thermal switch by following SERVICE
PROCEDURE IX. If the resettable thermal
switch is closed replace the simulated
resistive device
