Page: 36 / 74

1. Refer to page 3-4 for the servicing procedure
2. Set the Multiple meter scale to the R x1
3. Disconnect wires from cook-top elements
4. Touch the ohmmeter test leads to the (E1 & 1A)
and (E2 & 1A) the meter should indicate :
- (E1 & 1A)
32
Ω
± 10%
- (E2 & 1A) 55
Ω
± 10%
5. Touch the ohmmeter test leads to limiter
terminals 1A and 2A.the meter should indicate
continuity (0
Ω
)
6. Touch the ohmmeter test leads to limiter
terminals 1B and 2B.
With the temperature below 150˚F, the meter
should indicate an open circuit(infinite).
With the temperature above 150˚F, the meter
should indicate continuity (0
Ω
).
