Chamber/resistor
temperature probe alarm
Connect the probe to
the power board
Are the
chamber probes
connected to the
P10 or P12
sockets of
the board?
Measure the impedance
of the probe with the
multimeter set to ohm
Do you have
110 ohm at about
25 °C (77 °F)?
Replace the temperature
probe and
test the oven
at over
50
°C (
122
°F)
