Ensure that the thermocouple connection at the gas valve is fully

inserted and tight (hand tighten plus 1/4 turn).

Disconnect the thermocouple from the valve, place one millivolt lead

wire on the tip of the thermocouple and the other meter wire on the

thermocouple copper lead. Start the pilot and hold the valve knob in. If

the millivolt reading is less than 15mV, replace the thermocouple.

b. Defective valve.

If the thermocouple is producing more than 15 millivolts, replace faulty

valve.

Be sure the wire connections from the thermopile at the gas valve ter-

minals are tight and that the thermopile is fully inserted into the pilot

bracket.

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.
