Temperature sensor open or shorted. Here is what it means and how to clear it, easiest fix first.

OP / SH
May need a pro

OP or SH in the freezer or refrigerator temperature display means the control is getting a bad reading from that compartment's temperature sensor (thermistor). OP points to an open circuit, such as a failed sensor or broken wire. SH points to a short circuit. The compartment may then run too warm or too cold.

The code shows in whichever temperature display belongs to the faulty sensor, freezer or refrigerator. Frigidaire lists these as service codes on French-door models. Four-door models use a different set of service codes (Er T1 to Er T6) whose individual meanings Frigidaire doesn't publish, so check your manual.

Safety first: unplug the refrigerator (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix Frigidaire OP / SH

  1. Reset the refrigerator

    Unplug it for 30 seconds and plug it back in, or flip its breaker if you can't reach the plug. Note which display showed the code.

  2. Monitor temperatures

    Put a thermometer in each compartment and check it after a few hours. Keep the doors closed and move perishables to a cooler if the refrigerator rises above 40°F (4°C).

When to call a technician

If the code returns, a technician needs to test the sensor and its wiring at the control board. These checks involve electrical measurements behind interior panels.
