Whirlpool Electric Dryer

Here is the test you need

TEST #3 Heater Test

This test is performed when either of the

following situations occur:

✔ Dryer doesn’t heat

✔ Heat won’t shut off

This test checks the components making up the

heating circuit. The following items are part of

this system:

– Harness/connection

– Heater relay

– Thermal cut-off

– High limit thermostat

– Heat element

assembly

– Centrifugal switch

– Thermistor

– Machine control

electronics. See

ESD information,

page 1.

– Console

electronics

Dryer does not heat:

1. Unplug dryer or disconnect power.

2. Remove the toe panel to access the thermal

components. See figure 11, page 7. Locate

the components using figure 8.

3. Using an ohmmeter and referring to the

wiring diagram, measure the resistance from

the red wire at the thermal cutoff to the red

wire at the heater.

➔ If the resistance is about 10 ohms, go to

step 5.

➔ If an open circuit is detected, go to step 4.

4. Visually check the wire connections to the

thermal cutoff, high limit thermostat, and

heater. If connections look good, check for

continuity across each of these components.

Replace the one that is electrically open.

5. If no open circuit is detected, measure the

resistance between P2-5 (red/white wire) and

P2-6 (black wire) at the machine control

board.

➔ If 6–7 k ohms are measured, replace the

machine control electronics.

➔ If the resistance is less than 1 k ohm,

replace the thermistor
