Symptom Possible Cause Corrective Action
3. (Continued) b. Thermopile may not be
generating sufficient
millivoltage
Check the thermopile with a millivolt meter.
Take the reading at TH-TP&TP terminals
of the gas valve. The meter should read
325 millivolts minimum, while holding the
valve knob depressed in the pilot position,
with the pilot lit, and the ON/OFF switch
in the OFF position. Replace the faulty
thermopile if the reading is below the
specified minimum.
With the pilot in the ON position, disconnect
the thermopile leads from the valve. Take
a reading at the thermopile leads. The
reading should be 325 millivolts minimum.
Replace the thermopile if the reading is
below the minimum.
c. Defective valve Turn the valve knob to the ON position.
Place the ON/OFF switch in the ON
position. Check the millivolt meter at the
thermopile terminals. The millivolt meter
should read greater than 125mV If the
reading is acceptable, and if the burner
does not come on, replace the gas valve.
d. Plugged burner orifice Check the burner orifice for stoppage.
Remove stoppage.
e. Wall switch or wires are

outage problem.
a. Pilot flame may be too
high or too low, or blowing
