FLAME FAULT – After the Phase 7 non-coin microprocessor controller (computer) has verified that the gas valve signal was present throughout the Direct Spark Ignition (DSI) purge time and the DSI proof time, the Phase 7 non-coin microprocessor controller (computer) will continue to monitor the gas valve return signal. In the event that the gas valve return signal is lost anytime after the DSI proof time, the Phase 7 non-coin microprocessor controller (computer) will turn off the heat output and increase a counter. Once this fault condition occurs five (5) consecutive times, the Phase 7 non-coin microprocessor controller (computer) will interrupt the cycle, display “Flame Fault” condition, and go into a Fault Mode with a brief audio indication. If the basket (tumbler) temperature is above 100° F (38° C), the Phase 7 non-coin microprocessor controller (computer) will continue to display “Flame Fault”, while the dryer cools by running with no heat for 3 minutes or until the temperature drops below 100° F (38° C). Once the basket (tumbler) temperature is below 100° F (38° C), or the 3 minutes expire, the Phase 7 non-coin microprocessor controller (computer) will shut off ALL outputs and will remain in Fault Mode until the dryer is addressed.
BURNER PURGE FAULT – If the Phase 7 non-coin microprocessor controller (computer) detects the presence of the gas return signal before sending the heat signal out, the Phase 7 non-coin microprocessor controller (computer) will trigger a “Burner Purge Fault” condition and will go into Fault Mode with a brief audio indication. The dryer will run with no heat for 3 minutes or until the temperature drops below 100° F (38° C). Once the basket (tumbler) temperature is below 100° F (38° C), or the 3 minutes expire, the Phase 7 non-coin microprocessor controller (computer) will shut off ALL outputs and will remain in Fault Mode until the dryer is addressed.
BURNER HIGH-LIMIT FAULT – This routine monitors the burner high-limit switch. If the switch opens during the cycle while the heat is on, the dryer will display “Burner High-Limit Fault” and will go into Fault Mode with a brief audio indication. The Phase 7 non-coin microprocessor controller (computer) will check the basket (tumbler) temperature. If the exhaust probe temperature is above 100° F (38° C), the dryer will continue to display “Burner High Limit Fault”, while the dryer cools by running with no heat for 3 minutes or until the temperature drops below 100° F (38° C). Once the exhaust probe temperature is below 100° F (38° C), or the 3 minutes expire, the Phase 7 non-coin microprocessor controller (computer) will shut off ALL outputs and will remain in Fault Mode until the dryer is addressed.
CHECK CONTROL BOARD FUSE #2 – This routine identifies the opening of the main fuse (fuse 2) on the Phase 7 non-coin microprocessor controller (computer) board. If the fuse has opened, the Phase 7 non-coin microprocessor controller (computer) will not allow a cycle to begin and will display a “Check Control Board Fuse #2” condition. If the fuse has opened after the cycle has begun, it will still trigger the check main fuse fault. The dryer will shut off ALL outputs and will go into Fault Mode with a brief audio indication.
CLEAN LINT – This routine monitors the opening of the lint drawer switch and compares the time between openings to the lint cleaning frequency setting. This routine will first prompt the user to clean lint before locking out the dryer. Once the time between cleanings is equal to the Lint Cleaning Frequency setting, the display will prompt the user to clean lint. The lint cleaning frequency limits the amount of time the dryer will run before the Phase 7 non-coin microprocessor controller (computer) locks the dryer out for further use. If the lint drawer is not cleaned within 2 hours of run time, the Phase 7 non-coin microprocessor controller (computer) will be locked out.
EEPROM FAULT ### – Error in memory location. The ### indicates the location of the fault.
