Service Procedure VI
Gas Control Testing and
Replacement
Simulated Resistive Device Testing
Step 1. Position the power switch on the gas
control to the “OFF” position.
Step 2. Disconnect flammable vapor sensor
or simulated resistive device from
the gas control (model dependant).
Step 3. Using a multi-meter set to the ohms
setting, check resistance of the
flammable vapor sensor or simulated
resistive device. Resistance must be
between 3,000 ohms and 48,000
ohms. If outside of this range,
replace the simulated resistive
device.
CAUTION
DO NOT use a standard multi-meter probe for this
test. Doing so will damage connector. Use
special pin type electronic probes or small
diameter wire pins inserted into connector.
