Where SH comes from
Frigidaire printed this code in service data sheet 242321500 (FFHN2740PS/PE) and in sheet A01544701 (FGHG2366PF), two bottom-freezer ice and water models. SH means a shorted thermistor. Whether FF or FZ lights up beside it shows which thermistor is involved, fresh-food or freezer.
Owner steps and technician steps
For the owner the sheets give nothing to try; the helpful contribution is a note of which side, FF or FZ, carries the code.
Inside System Diagnostic Mode, a thermistor test returns SH for a short circuit and OP for an open one.
A technician then measures the shown temperature against a gauge reading taken at the thermistor.

SY CE: the control panel lost contact with the main board
For SH on a refrigerator in San Francisco or the wider Bay Area, contact Frigidaire refrigerator repair at (415) 319-6371. We will want the model number and to hear whether SH sits beside FF or FZ.
Model compatibility: Frigidaire reuses codes across series and model years, so SH may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
SH reports a shorted fresh-food (FF) or freezer (FZ) thermistor on Frigidaire bottom-freezer ice and water refrigerators.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
