Dacor Refrigerator Error Code F1

F1 on a Dacor refrigerator signals an air sensor fault, meaning the control board has detected a problem with the thermistor that monitors compartment air temperature. As a protective response, the control board shuts off the compressor when this fault is active. The refrigerator will not cool properly until the sensor fault is diagnosed and resolved.

Because the F1 fault causes the compressor to shut off, the refrigerator will gradually lose its cold temperature. Food safety depends on how long the fault has been active and the ambient temperature of the room. As a general guideline, perishables should not remain above 40 degrees Fahrenheit for more than two hours, so addressing the fault promptly is important.

A power reset, such as unplugging the unit for a few minutes and restoring power, may temporarily clear the F1 code if the fault was caused by a transient condition. However, if the underlying issue is a failed sensor, damaged wiring, or a faulty control board, the error will return as soon as the refrigerator attempts normal operation. A reset is useful for ruling out a one-time glitch but should not be relied on as a fix.

Some causes of the F1 error, such as a loose sensor connector or a visually damaged wire, can be addressed by a knowledgeable DIYer. However, accurately diagnosing a failed thermistor requires a multimeter and familiarity with reading resistance values. Replacing the control board, if needed, is also within DIY range but carries more risk if the wrong component is condemned, so professional diagnosis is advisable when basic checks do not resolve the fault.

Repair costs vary depending on which component has failed. Replacing an air sensor thermistor typically runs in the range of $50 to $150 for parts and labor if the sensor alone is at fault. If the wiring harness needs repair the labor cost may increase, and a main control board replacement can bring total costs to the range of $200 to $450 or more depending on the specific model and service rates in your area.
