MANUAL RESET HI-LIMIT INSTRUCTIONS

FOR DUAL TIMER OR PHASE 5 WITHOUT HEAT FAULT

This dryer was manufactured with a manual reset burner hi-limit and basket (tumbler)/lint chamber thermostat.
If either manual reset hi-limit thermostat is open prior to the start of the drying cycle, or during the cycle, the dryer
will not recognize the open state of the hi-limit thermostat and will start or continue through the drying cycle with
no heat.  Manual reset hi-limit thermostat 

must be 

reset manually.

This hi-temperature condition may be caused due to a restricted exhaust, poor airflow, or improper burner oven
operation.

The location of the burner manual reset hi-limit switch is on the right side of the burner box. The basket (tumbler)
/lint chamber manual reset hi-limit is located in the lint chamber just under the basket (tumbler).

WARNING:

Discontinue power to dryer before attempting to reset hi-limit.

IMPORTANT

This dryer is equipped with a burner

hi-limit and tumbler/lint chamber hi-limit
thermostat which must be reset manually.

WARNING:

 Discontinue power to dryer

before attempting to reset hi-limit.
