Displayed (flashing) when the meat probe is not connected when a probe-required function is selected, or when the oven sensor or probe is open/shorted.

First step from the service manual

Connect the meat probe to the receptacle and touch the food temp pad again, or check probe resistance (~50K ohms at 75°F).

What prob means on a Camco range

The PROB error code on a Camco range flashes when the control detects a fault condition related to the meat probe circuit. This occurs in two primary scenarios: the user has selected a probe-dependent cooking function without a probe connected to the receptacle, or the control has detected that the oven sensor or probe circuit is electrically open or shorted. The probe system relies on a thermistor-based sensor that changes resistance predictively with temperature. At approximately 75 degrees Fahrenheit, a healthy probe should measure around 50K ohms. A reading significantly above or below this value indicates a damaged or failed probe.

When a probe-required cooking mode is selected, the range expects to see a valid resistance signal from the probe receptacle. If no probe is inserted, or if the probe's internal thermistor has failed open or short, the control interprets this as a fault and flashes PROB to alert the user. An open circuit condition typically means the thermistor or its lead wires have broken internally, producing infinite resistance. A shorted condition means resistance has collapsed near zero, often caused by physical damage, moisture intrusion, or heat exposure to the probe cable or connector.

The oven temperature sensor (RTD or thermistor) can also trigger this code if it develops an open or shorted condition, since the control monitors both the probe and the oven sensor through related circuitry. Diagnosing the source requires checking resistance at both components and inspecting the wiring and receptacle for corrosion, damage, or loose connections.

Common causes of prob

  1. 01

    Meat probe not connected

    Wiring / connection

    The most frequent trigger is simply selecting a probe cooking function without the meat probe inserted into the oven receptacle. Plug the probe in securely and re-select the food temperature setting.

  2. 02

    Damaged or failed meat probe

    Part replacement

    If the probe has been bent, submerged, or exposed to excessive heat at the cable or connector, the internal thermistor can fail open or short. Test resistance at the probe connector: a working probe reads approximately 50K ohms at 75 degrees Fahrenheit. A reading of zero or infinity indicates a failed probe.

  3. 03

    Corroded or damaged probe receptacle

    Part replacement

    The receptacle mounted inside the oven cavity can accumulate grease, moisture, or corrosion that disrupts the electrical connection. Inspect the receptacle for buildup or bent contacts and clean or replace as needed.

  4. 04

    Open or shorted oven temperature sensor

    Part replacement

    The oven's internal temperature sensor can also cause the PROB code if its resistance has drifted far out of range due to an open or short circuit. Check the sensor's resistance with a multimeter and compare to the expected specification for the model.

  5. 05

    Damaged probe wiring or connector

    Part replacement

    Wiring between the probe receptacle and the control board can develop breaks or shorts from heat exposure or physical damage. Inspect the wiring harness for melted insulation, pinched wires, or loose connector pins.

Frequently asked questions about prob

What does prob mean on a Camco range?
The PROB code on a Camco range indicates a problem with the meat probe circuit. It flashes when a probe-required cooking function is selected without the probe connected, or when the probe or oven sensor is detected as electrically open or shorted. Checking whether the probe is properly inserted is the first step. If the probe is connected and the code persists, the probe or sensor may need testing or replacement.
How do I fix the PROB error on my Camco range?
Start by plugging the meat probe securely into the receptacle inside the oven cavity, then press the food temperature pad again to re-enter your cooking settings. If the code continues, test the probe resistance using a multimeter: at room temperature (around 75 degrees Fahrenheit), a good probe should read approximately 50K ohms. A reading of zero or infinity means the probe has failed and needs to be replaced. Also inspect the receptacle and wiring for corrosion or damage.
Is the PROB error on a Camco range a safety concern?
The PROB code itself is a control alert rather than a safety emergency, but it does prevent probe-dependent cooking modes from operating as intended. If the oven temperature sensor is causing the code, cooking accuracy may be compromised and the oven should not be used for precision cooking until the sensor is inspected. A faulty probe left plugged in during high-temperature cooking could also be a concern if the cable is damaged, so inspect the probe and wiring before continued use.
Will resetting the Camco range clear the PROB error code?
Resetting the range by disconnecting power may temporarily clear the display, but the code will return as soon as a probe function is selected if the underlying issue has not been resolved. A reset does not repair a failed probe, damaged receptacle, or faulty oven sensor. Addressing the root cause, such as connecting the probe or replacing a defective component, is necessary to permanently clear the code.
How much does it cost to fix a PROB error on a Camco range?
Repair costs depend on what component has failed. A replacement meat probe typically costs in the range of $20 to $60 for the part. An oven temperature sensor replacement part generally falls in the $25 to $80 range. If professional labor is required for wiring repairs or component replacement, total repair costs including labor can range from $100 to $250 or more depending on the service provider and extent of the repair.
