Why is my McDonald's Commercial Food Equipment product undercooked or overcooked?
- A
  alexandersherylAug 20, 2025
  Several factors can cause undercooked or overcooked food. The release material sheet might be worn and needs replacement. The upper platen or lower grill surface may not be clean, with carbon build-up requiring thorough cleaning following closing procedures. The cooking time or temperature could be incorrect, requiring you to reset or adjust the processor control accordingly. The preset gap height may also be incorrect, or a heating zone might not be heating, both of which require a service technician.

What to do if my McDonald's Commercial Food Equipment exhaust hood and grill will not turn on?
- M
  Maria MasseyAug 22, 2025
  If the exhaust hood and grill do not turn on, first, check if the restaurant circuit breaker has tripped and reset it if necessary. Next, ensure the fan disconnect switch on the roof is in the ON position. Also, verify the fan interlock cord is properly connected. If these steps don't resolve the issue, the fan interlock switch may be faulty, requiring a service technician.

  Jeremy WelchAug 25, 2025
  If the grill alone won't turn on, first, check if the ansul reset has tripped and press the ansul reset button. If that doesn't work, the fan interlock switch or the fuse in the control box might be faulty, requiring a service technician.

Why is my McDonald's Commercial Food Equipment product not cooking evenly?
- T
  Tony AllenAug 27, 2025
  Uneven cooking can result from a few issues. The upper platen or lower grill surface might not be clean or may have carbon build-up, so you should follow closing procedures to clean them properly. A worn release material sheet should be replaced. The platen may not be level and needs re-leveling. Additionally, insufficient air pressure or an incorrect preset gap height can cause this issue, both of which require a service technician.

  thomasdarrellAug 28, 2025
  If the center heat zones aren't heating and the display shows “PROBE FAILURE,” check the power connection and reset the restaurant circuit breaker. If the problem persists, the contactor, heater element, high limit switch, or solid state relay might be faulty, all requiring a service technician.

What to do if my McDonald's Commercial Food Equipment upper platen will not stay in the COOK or STANDBY position?
- A
  Andrew JonesAug 30, 2025
  If the upper platen won't stay in either the COOK or STANDBY position, first ensure the temperature is sufficient by waiting until the indicator LEDs turn green. If it still doesn't work, the control harness, processor control, interface board, latch switch, latch solenoid, or pneumatic system could be faulty, all requiring a service technician.

  If the product isn't being recognized, ensure the grill is set to Auto Product Recognition mode by correcting the product menu settings.
