THERMAL CUTOFF (TCO)
(GAS DRYERS ONLY)

Refer to page 4-10 for the procedure for ac-
cessing the thermal cutoff (TCO).
1.  Unplug dryer or disconnect power.
2.  Turn off gas supply to dryer.
3.   Disconnect the wire connectors from the 

TCO terminals.

4.  Set the ohmmeter to the R X 1 scale.
5.  Touch the ohmmeter test leads to the TCO 

terminals.  The  meter  should  indicate  a 

closed circuit (0 

Ω

).

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.
