Meat probe not working, reads over 400 - Masterbuilt ESQ30B Smoker

Hello, Waldy -

Then, purchase a new meat thermometer / probe and put the non-working one in electronics recycling.

Best wishes.

faulty meat probe, probably a factory defect, if still covered by warranty, return oven for replacement.

You will need to replace the jack for the probe. Here is the part to order.

Yes- give factory a call- they will likely send out a probe

It is possible that the therrmometer has over shot the limit set on it .It can be spoiled because the hat was in direct contact with the probe and has resulted in the failure of the unit.

Error U80: Shorted meat probe

1) Food, moisture, or other substance is in the socket or on the oven connection end of the meat probe. Check: Verify proper operation with new probe (replace probe). If still fails with new probe check wiring of housing to eliminate shorting to sheet metal. Solution: Clean socket and meat probe.

2) Bad meat probe (shorted). Check:Use new meat probe to test for correct values in the service screens. Solution: Replace meat probe.

3) Shorted socket or wiring. Check: Test socket at connector J20 on relay board. Solution: Replace meat probe socket.

Functionality when error U80 reported: Cooking and cleaning are available but meat probe options will not be available.

User action/solution:
1) Verify oven connection end of meat probe is clean and no food, moisture or other substance in is the meat probe socket.
2) Call for service.

I left mine in a hot tub for well over an hour. It started reading room temp at about 125 degrees. It worked for me to put the thermometer in the freezer until the readings were correct. hope this works for you.

I have the same problem. The problem is the probe went bad. I had a friend with another sumbeam digital probe (the mavrick) put that probe into mine and the temperature reading was working properly. So, now I am looking for a replacement probe. but looks like I will have to just buy another digital meat probe.

replace the probe
