Why does the Shel lab Oven motor make noise?
- C
  Christine CarterSep 4, 2025
  If the Shel lab Oven motor makes noise, ensure that the fan or blower wheel is not contacting its housing. Adjust the motor mounting bracket position to re-center the fan or blower wheel, if necessary. Check the fan or blower wheel for damage or an out-of-balance condition, and replace it if necessary. Turn the motor shaft to ensure it spins freely; if it binds or the bearings make noise, replace the motor.

Why Shel lab Oven unit will not heat over a temperature that is below set point?
- D
  Debbie OlsonAug 28, 2025
  If the Shel lab Oven will not heat over a temperature that is below the set point, confirm that the fan is moving and that the amperage and voltage match the data plate, and check for air movement in the chamber. Ensure that the set point is set high enough, and turn the Safety Thermostat all the way clockwise to see if the OTP light comes on. Check the connections to the sensor.

  If your Shel lab Oven temperature is too high, the controller or wiring may have failed, in which case you should contact Customer Service. Also, trace the wire from the display to the probe and move the wire to check for intermittent problems, as the probe might be unplugged, broken, or have a broken wire to the sensor.

Why is the temperature too low in my Shel lab Oven?
- E
  Emily MaloneAug 23, 2025
  If the Shel lab Oven temperature is too low, wait for the display to stabilize after opening the door. Allow several hours for the oven to warm up and stabilize after a power failure or being turned off. Compare the current draw to the data plate to check for element failure. Confirm that the Safety Thermostat is operating correctly by observing the front panel lights to rule out high limit failure. Check all functions and wiring against the schematic, especially in recently worked-on areas, to identify any wiring problems. Finally, inspect the control panel for loose connections.
