Error code77
ApplianceCooktop
Quick summary
The heat sink temperature sensor on the right side of the induction housing assembly has a break. This code appears in service data sheet 318200282 Rev B, an older sheet for a 30-inch induction cooktop with ceramic glass.
The single corrective action
Replacing the Right Side Generator Circuit Board is the whole list, and a technician does it.
Until then, leave the right side zones switched off.
When 77 stays lit on a cooktop in San Francisco or elsewhere in the Bay Area, (415) 319-6371 is the number to ring, or open Frigidaire cooktop repair. Keep the model number handy and say that the right side zones are affected.
Model compatibility: Frigidaire reuses codes across series and model years, so 77 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
Heat sink temperature sensor break, right side cooking zones.
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.
