What does Doyon FOOD PROBE ERROR mean?
The ECM-1 control can bake by food temperature using a probe placed in the product. When the control sees a signal that indicates the food probe is defective, it shows FOOD PROBE ERROR and goes to Off mode. The manual lists one cause, a defective food temperature probe. It does not give separate repair steps. The troubleshooting table does not list this message, and the diagnostics section states only the error. That is useful for a technician: it means no manual sequence exists to follow, and the probe itself and its plug and lead are the place to look. For an operator, the practical points are to make sure the probe is plugged in as it should be and not damaged, and not to bake until the oven responds normally again.

Other likely causes — what usually sits behind FOOD PROBE ERROR on this control. A technician confirms which one it is before any part is replaced.
- Probe plug not fully seated in its socket
- Probe lead crushed or heat-damaged from oven door or racks
- Food probe tip or cable damaged by cleaning
- Probe socket on the oven corroded
Safe checks before calling for service
- Switch off the oven and let it cool.
- Look at the food probe lead for cuts, kinks or burn marks.
- Unplug and firmly replug the probe at its socket.
- Power the oven up to see whether the error clears. If it comes back, call for service.
- Tell the technician whether the probe was damaged and whether the error returns with no probe in use.
How a technician diagnoses FOOD PROBE ERROR
- Read the display and confirm FOOD PROBE ERROR.
- Inspect the probe, its lead and the socket.
- Measure probe resistance and compare it with the probe's table.
- Try a known good probe to confirm whether the probe or the oven input is at issue.
- Replace the probe, or repair the socket, then confirm a normal reading.
- Socket and control input checks reach live circuits behind panels.
- Comparing probe resistance needs a meter and the correct probe table.
- The manual gives no steps for this message, so diagnosis relies on a technician's testing.
How FOOD PROBE ERROR differs from similar codes
CAVITY PROBE ERROR lists a connection check and a replacement step. For FOOD PROBE ERROR the manual states only the error.
