How do I troubleshoot no control box cooling on my Lincoln Impinger 3270 CE Convection Oven?
- M
  Michelle WilliamsonAug 25, 2025
  If there's no control box cooling in your Lincoln Convection Oven, start by checking the main circuit breakers and reset them if required. If problems persist, call the power company. Also, check the 15 Amp fuse and fuse holder, replacing them if necessary. Check the continuity between the main oven switch terminals. Ensure 120 VAC is at the cooling fan motor. If voltage is present but the motor doesn’t turn, with the power off, check the motors for shorts or opens and check for a locked rotor. Replace the fan if necessary.

Why does the flame go out on my Lincoln Impinger 3270 CE?
- A
  Anna KelleyAug 27, 2025
  If the flame on your Lincoln Convection Oven won't stay on, the ignition control keeps the gas control valves energized for 6 seconds. The hot surface igniter must sense a flame within this time, requiring a minimum of 0.8 micro-amps D.C., or the ignition control will go into lockout. If you detect a flame for only the 6-second trial, check the flame sensing operation. If there is sufficient micro-amp current and the 120VAC polarity is correct but the flame will not stay lit, check for proper ground connection for the ignition control. If ground is good, replace the ignition control.

What to do if there is no automatic control box cooling in my Lincoln Convection Oven?
- C
  Courtney LandryAug 31, 2025
  If there's no automatic control box cooling on your Lincoln Convection Oven, check the circuit breakers and reset them if required. If issues persist, contact the power company. Also, check the 15 Amp fuse and fuse holder, replacing them if necessary. Check the cooling fan thermostat, which closes at 120°F and opens at 100°F. With the thermostat preheated, check for continuity; if the switch is open, replace it. Ensure 120 VAC is at the cooling fan motor. If voltage is present, with the power off, check for a locked rotor and check the motor for shorts, opens, or grounds.

Why does the conveyor on my Lincoln Impinger 3270 CE Convection Oven run, but there is no speed control?
- L
  Lance JuarezSep 3, 2025
  If the conveyor runs but there's no speed control on your Lincoln Convection Oven, and there is voltage supplied to the hall effect sensor, check for frequency output from the hall effect sensor. Measure frequency across the yellow and white wires at the motor connector. Frequency readings should be between 25 – 500 Hz. If these readings are not achieved, replace the conveyor motor. If the hall effect sensor readings are correct but there is no speed indicated on the display, replace the oven control.

Why does my Lincoln Convection Oven have intermittent heating issues?
- C
  Crystal CarterSep 9, 2025
  The main fan motors and the burner blower motors in the Lincoln Convection Oven are equipped with internal thermal protection and will cease to operate if overheating occurs. As the motors overheat and then cool, this will cause the units to cycle on and off intermittently. Improper ventilation or improper maintenance may cause this. Also, most of the problems listed under “oven will not heat” can cause intermittent failure.
