GE Microwave Error Code BAD PROBE

BAD PROBE on a GE microwave means the control board is detecting a problem with the temperature probe circuit. This typically means the probe is not fully inserted into the outlet on the microwave cavity wall, or the probe is defective. The microwave displays this error to prevent a cooking cycle from running without a properly functioning probe connection.

The BAD PROBE error itself is not a safety hazard, but it will prevent the microwave from completing a probe-based cooking cycle. You can still use the microwave for standard timed cooking without the probe connected. Do not attempt to defeat or ignore the error if you need accurate internal food temperature monitoring, as an undetected defective probe could result in undercooked food.

If the fix is simply reinserting the probe, there is no cost involved. A replacement temperature probe typically costs anywhere from $15 to $50 depending on the model and supplier. If the cavity wall outlet needs replacement, parts and labor from a technician could range from $75 to $200 or more. Control board replacement, if required, is generally the most expensive repair and can range from $150 to $400 depending on the unit.

Start by removing the temperature probe and reinserting it firmly into the cavity wall outlet until it is fully seated. If the error persists, inspect the probe cord and plug for any visible damage and check the outlet for debris or corrosion. If the probe appears damaged, replacing it with a compatible probe should resolve the issue. If both the probe and outlet appear fine but the error remains, a technician should test the outlet receptacle and control board.

A power reset alone is unlikely to permanently clear the BAD PROBE error if the underlying problem has not been corrected. The error will return as soon as the microwave checks the probe circuit again. The correct approach is to either properly insert the probe, clean the outlet, or replace the defective component before the error will stay cleared.
