Frigidaire refrigerator SH code: shorted temperature sensor

A temperature sensor (thermistor) is shorted, so the control gets a false reading. SH in the freezer display points to the freezer sensor, and SH in the fresh food display points to the fresh food sensor. A failed sensor or pinched wire is the usual cause.

Likely causes

1. Failed thermistor
