Why does the Lincoln 2500 cooling fan continue to run?
If the cooling fan in your Lincoln Oven continues to run, the control box thermostat may be the issue. The thermostat should close at 120°F (49°C) and open at 100°F (38°C). Keep in mind that the thermostat will remain closed if the control box temperature stays above 120°F (49°C). Check the cooling fan thermostat.
Why does the conveyor motor on my Lincoln Commercial Food Equipment run, but the speed control is not working?
If the conveyor motor on your Lincoln Commercial Food Equipment runs but the speed control is intermittent or non-existent, check the following: 1. **Transformer:** Verify the 208/240 input voltage to the transformer. If there's no voltage, check the On/Off switch (S) and the Control Box Hi-Limit (T1) for continuity. Also, check the 5 amp fuses (F1, F2) for continuity. If voltage is present, check for 24VAC output from the transformer. If no voltage is present, check the circuit breaker (CB) on the output of the transformer; if there's still no secondary voltage from the transformer, replace it. 2. **Conveyor Control:** Check for 2-29VDC output from the conveyor control at J3-2 and J3-1. If there's no voltage present but 24 VAC input at J1 and J2, replace the main control board.
What should I do if my Lincoln Commercial Food Equipment has no digital display?
If there is no digital display on your Lincoln Commercial Food Equipment, check the following: * **Transformer:** Check the 208/240 input voltage to the transformer. If no voltage is present check the On/Off switch (S) and the Control Box Hi-Limit (T1) for continuity. Also check 5 amp fuses (F1, F2) for continuity. Check for 24 VAC at J1 and J2 power into the digital control. Check circuit breaker (CB) on output of transformer. If no secondary voltage from transformer replace transformer. If secondary voltage is present then replace main control board.
Why does the cooling fan on my Lincoln Commercial Food Equipment keep running?
If the cooling fan on your Lincoln Commercial Food Equipment continues to run, check the cooling fan thermostat. The thermostat should close at 120°F (49°C) and open at 100°F (38°C). Keep in mind that the thermostat will remain closed if the control box temperature stays above 120°F (49°C).
