Dual Surface Unit(Lf) - LG LRE30453SW Service Manual

Components
Dual surface element
: Left Front(LF)
Test procedures
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 :
32 Ω ± 10%
- (E1 & 1A)
55 Ω ± 10%
- (E2 & 1A)
1A
5. Touch the ohmmeter test leads to limiter
terminals 1A and 2A.the meter should indicate
continuity (0 Ω)
1A
2A
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).
