What OP means.

OP on the freezer temperature display can mean two things. If the freezer door is genuinely open, OP is the controller telling you to close it — common on Frigidaire side-by-sides where the door switch is sensitive. If the door is closed and OP still shows, the freezer temperature sensor has gone open-circuit (failed or wire disconnected). Without the sensor the controller cannot manage freezer temperature accurately and falls back to a backup duty cycle.

Most common causes.

  • Freezer door not fully closed (most common — check first).

  • Freezer thermistor failed open.

  • Wire harness to sensor damaged.

  • Connector at the back of the freezer corroded.

Try this first — safe DIY troubleshooting.

  1. Confirm the freezer door is fully closed and gasket is sealing.

  2. Unplug the unit for 5 minutes; restore power.

  3. If OP returns within an hour with the door closed, the sensor or wiring needs service.

  4. Watch for frost forming on items along the rear wall — that confirms sensor failure.

What your neighbors said this month.

  • I couldn't recommend this company more highly. I have used them several times and found Ivan to be knowledgeable, responsive, honest and courteous. He has saved me from buying a new refrigerator twice and unlike so many vendors, he is always able to diagnose the problem quickly and always knows how to fix it. If you want someone reliable who truly knows his craft and is always fair and reasonable, call We Fix Fridges!

  • We have used this company several times now. I wanted to leave a review because Ivan really went above and beyond for this last repair the day before a big holiday weekend. He saved us! 100% recommend him. Besides being so knowledgeable which helps with diagnosis to repairs he is courteous and timely and we have found his prices to be very fair. It's hard to find a trustworthy reliable repair person. We have Ivan on text now!

  • Highly recommended. Been in business with Ivan 3 different times with different appliances and all were satisfactory with problem fixed. He even figured out an indirect minor issue and fixed it for us with no charge without us asking for it. Ivan will be the first one I call in any cases of an appliance that needs repair.
