COMPONENT TESTING

Before testing any of the components, perform the following checks:

•Control failure can be the result of corro- sion on connectors. Therefore, disconnect- ing and reconnecting wires will be neces- sary throughout test procedures.

•All tests/checks should be made with a VOM or DVM having a sensitivity of 20,000 ohms-per-volt DC, or greater.

•Check all connections before replacing com- ponents, looking for broken or loose wires, failed terminals, or wires not pressed into connectors far enough.

•Resistance checks must be made with power cord unplugged from outlet, and with wiring harness or connectors disconnected.

For any additional test beyond what is covered in this Component Testing section, refer to the

Tech Sheet that is supplied with the product.

WARNING

Electrical Shock Hazard

Disconnect power before servicing.

Replace all parts and panels before operating.

Failure to do so can result in death or electrical shock.

HEATER

Refer to page 4-10 for the procedure for ser- vicing the heater.

1.Unplug dryer or disconnect power.

2.Disconnect one of the wire connectors from the heater terminal block.

3.Set the ohmmeter to the R X 1 scale.

4.Touch the ohmmeter test leads to the ter-

minals on the heater terminal block. The meter should indicate between 7 and 12 Ω.
