What Does Error PROBE Mean?

The GE microwave PROBE error indicates a malfunction in the temperature probe circuit, which can prevent the microwave from heating food properly or cause erratic temperature readings. This issue typically arises when the temperature probe is not inserted correctly or is detected as open during temperature-based cooking functions. The error will persist until the probe circuit issue is resolved.

Common Symptoms:

  • Error “PROBE” shown on display when attempting temp/sensor cook function
  • Microwave otherwise operates normally for basic microwave functions
  • Error persists until probe circuit issue is resolved

Possible Causes

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

How to Fix Error PROBE

DIY Fix Check probe and retry

  1. Ensure microwave is off and safe to approach
  2. If your model uses a temperature probe, make sure it is inserted fully into both the receptacle in the microwave cavity wall and the food
  3. Try a basic cook function (not temp/sensor cook) to confirm other functions work
  4. If error persists with a temp cook, proceed to further inspection or technician

Technician Only Inspect and test probe circuit

  1. Unplug microwave and discharge high‑voltage components
  2. Remove microwave cavity panels to access the temperature probe, receptacle, and wiring
  3. Visually inspect wiring harness and connector for damage or loose connections
  4. Use a multimeter to check continuity of the probe and wiring to the control board
  5. Replace faulty probe, receptacle, or wiring harness as needed

Parts needed: Temperature probe, Probe receptacle, Wiring harness

🛑 When to Call a Pro:
  • If visual inspection or continuity tests show damaged wiring or components
  • If error persists after basic probe re‑insertion and continuity checks
  • If microwave disassembly is needed beyond probe access
