3-22
TEST PROCEDURE RESULTCOMPONENT
a) Normal = 155 K to 350 K
ohms @ 68˚F.
Set the ohmmeter to the
R x 10 K
scale.
Remove the 6-pin connector from
the circuit board and measure
across terminals 5 & 6.
b) Abnormal = Infinity, or
zero ohms (a short).
Convection Thermistor
Set the ohmmeter to the
R x 1
scale, and measure across the
terminals.
Convection Heating Element
(with leads disconnected)
a) Normal = 9 to 40 ohms @
68˚F ±2˚.
b) Abnormal = Infinity, or
zero ohms (a short).
Set the ohmmeter to the
R x 1
scale.
Remove the 3-pin connector from
the circuit board and measure the
resistance between:
a) Red & white wire terminals.
b) White & yellow wire terminals.
Gas Sensor
b) Infinite.
a) 20 ohms @ 68˚F ±2˚.
