MANUAL RESET HI-LIMIT INSTRUCTIONS

FOR PHASE 6 MODELS

This dryer was manufactured with a manual reset burner hi-limit and tumbler (basket)/lint chamber hi-limit thermostat which is monitored by the Phase 6 computer. If either manual reset thermostat is open prior to start of the drying cycle, the dryer will start momentarily and then shut down, the Phase 6 computer will display an error code with an audio indication. If the tumbler (basket)/lint chamber hi-limit thermostat is open, the display will read “dRUM SAFETY FAIL.” If the burner hi-limit thermostat is open, the display will read “bURNER

SAFETY FAIL.”

If either manual reset hi-limit thermostat opens during a drying cycle, the display will show the applicable error code described above along with an audio indication. If the drum temperature is above 100º F (38º C), the dryer will continue to run with no heat for three (3) minutes or until the drum temperature has flattened below 100º F (38º C). The clear/stop button on the Phase 6 keyboard (touchpad) must be pressed to clear the error condition. The open manual reset hi-limit thermostat must be reset “manually” prior to the start of the next cycle.

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

The location of the burner hi-limit is on the right side of the burner box and the tumbler (basket) hi-limit is located in the lint chamber area.

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.
