What Does Error PROBE Mean?

The Monogram Microwave PROBE error indicates an issue with the temperature probe sensor, which may not be properly inserted or recognized. This can lead to erratic temperature readings and prevent the start or completion of temperature-based cooking cycles. Ensure the probe is securely connected, as an open or faulty circuit could be the underlying cause.

Common Symptoms:

  • Microwave displays the text "PROBE" on the control panel
  • Temperature‑based cooking cycles do not start or are cancelled
  • May occur immediately when selecting a probe cook function

Possible Causes

  • Temperature probe not properly inserted or not detected (medium)
  • Open or faulty temperature probe circuit (medium)

How to Fix Error PROBE

DIY Fix Check and reseat the temperature probe

  1. Ensure the microwave is idle, not actively cooking
  2. Open the microwave door and locate the temperature probe receptacle on the cavity wall
  3. Firmly insert the temperature probe into the receptacle and ensure the food‑end of the probe is properly positioned in the food item as per the recipe
  4. Cancel the PROBE error and attempt the probe cook function again

Technician Only Inspect and test the temperature probe and associated wiring

  1. Disconnect power to the microwave at the circuit breaker
  2. Gain access to the temperature probe connector and harness inside the microwave (refer to service manual)
  3. Visually inspect the probe wiring harness for breaks, kinks, or loose connections
  4. Test the temperature probe resistance with a multimeter to check for an open circuit; compare with manufacturer specifications
  5. Replace the probe or repair wiring if open or damaged, then reassemble and restore power

Parts needed: Temperature probe assembly, Probe wiring harness/connectors

🛑 When to Call a Pro:
  • If the PROBE code persists after confirming proper probe insertion and basic checks — call for authorized Monogram service
  • If internal wiring or sensor testing is required, do not proceed without proper training due to high‑voltage components in microwaves
