Monogram Slow Preheat or Insufficient Heating

Oven takes excessively long to preheat or never reaches the set temperature on a Monogram range.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Weak or partially failed bake element, One leg of power missing (120V instead of 240V), Faulty temperature sensor, Door not sealing properly

Safety first: Turn off power before testing electrical components.

Check power supply: Have an electrician verify that both legs of 240V power are present at the range.
Inspect elements: Ensure both bake and broil elements glow during preheat (some models use both). Replace any element that does not heat fully.
Test sensor: Measure oven sensor resistance at room temperature (~1080 Ω). Replace if out of spec.
Door seal: Inspect the door gasket and hinges for proper sealing. Replace worn gaskets.
