Whirlpool MED / GD 9600S, MED / GD 9700S manual Test #3 Heater Test, Dryer does not heat

•If belt switch is okay and there is still an open circuit, check and repair the wir- ing harness.

•If the Start winding is in question and the resistance is much greater than 4 ohms, replace the motor.

9.Door switch problems can be found using the Diagnostic Tests on page 6-2; how- ever, if this was not done, the following (step 10) can be done without applying power to the dryer.

10.Connect the ohmmeter test leads to the electronic control board at P1-2, (neutral, white wire), and P1-3 (door, blue wire).

With the door closed, the ohmmeter should indicate a closed circuit (0 to 2 Ω). If not, replace the door switch assembly.

TEST #3: HEATER TEST

This test is performed when either of the fol- lowing situations occur:

•Dryer does not heat

•Heat will not 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 fuse (gas dryer only)

•Thermal cutoff (electric dryer only)

•High-limit thermostat

•Gas burner assembly (gas dryer only)

•Heat element assembly (electric dryer only)

•Centrifugal switch

•Thermistor

•Electronic control board

•Console electronics & housing

•Gas supply (gas dryer only)

Dryer does not heat:

1.Unplug dryer or disconnect power.

2.Remove the toe panel to access the ther- mal components.

3.Gas Dryers Only:

a)Perform TEST #3b (Thermal Fuse Test). If the thermal fuse is okay, proceed to step b.

b)Connect the ohmmeter test leads to the red wire and the blue wire of the high- limit thermostat.

•If there is an open circuit, replace the high-limit thermostat.

•Otherwise, proceed to step c.

c)Perform TEST #3c (Gas Valve Test). If this is okay, replace the electronic con- trol board.
