The range is unplugged and a meter is put on the lower sensor. The expected figure is 1,090 ohms at 77 degrees F. A sensor that misses it by more than 100 ohms is replaced. The electric and the double-oven gas models share this test and its limits.
The 362 freestanding range
Unplug the range, disconnect the sensor, and read it with a volt/ohm meter. About 1100 ohms at room temperature is normal. A reading more than 200 ohms away calls for a new sensor, while a normal reading moves the blame to the electronic control board, which is then replaced.
These tests need a meter, so they are technician work. Owners should unplug the range and note which family theirs belongs to.
F4/E1: a shorted meat probe rather than an oven sensor.
Kenmore range service in San Francisco and nearby
A Kenmore range showing F4 can be looked at by a technician anywhere in San Francisco or the Bay Area; ring (415) 825-6393 to set it up. Please have the code, the model number (721 or 362 series) and a note of anything you tried handy. Kenmore range repair gives the wider picture.
Model compatibility: Kenmore reuses codes across series and model years, so F4 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
