Electrolux Refrigerator Error Code LO F

LO F indicates that the Perfect Temp Drawer exceeded its under-temperature timeout. The drawer's temperature dropped below its low-cool limit and stayed there longer than the control board permits. This error points to a problem with the drawer thermistor, the internal heater, or the damper that controls airflow into the compartment.

Resetting the refrigerator by unplugging it or cycling the control board may temporarily clear the LO F code, but the error will return if the underlying fault is not corrected. The code is triggered by a timed condition, so as long as the thermistor, heater, or damper remains faulty, the control board will detect the out-of-range temperature again and repost the error.

Repair costs vary depending on which component has failed. A thermistor replacement is typically the least expensive repair, with parts generally in the range of $15 to $50. A heater element or damper assembly replacement can bring parts costs to roughly $40 to $120, with labor adding $100 to $200 or more depending on your location and the technician's rate. Diagnosing the specific failed component first will help you get an accurate estimate.

Some steps are accessible to a knowledgeable DIYer, such as inspecting the damper for ice buildup, clearing frost, and checking wiring connectors for corrosion or looseness. However, testing the thermistor resistance, verifying heater continuity, and confirming the damper actuator operates correctly require a multimeter and some familiarity with appliance diagnostics. Replacing components like the heater or damper assembly is a moderate-difficulty repair.

Food stored in the Perfect Temp Drawer may be at risk because the drawer's temperature is not being regulated correctly. The main refrigerator and freezer compartments are typically unaffected, but you should avoid relying on the PTD for temperature-sensitive items like meat or dairy until the fault is diagnosed and repaired. Address the issue promptly to avoid food spoilage.
