Error code35/75
ApplianceCooktop
Voltage too low
When the display shows 35 or 75, the induction housing assembly is getting AC input voltage below the level it needs. Codes 30 and 70 are the mirror image, and the checks are the same. Both belong to the earlier 30-inch ceramic-glass induction cooktop in sheet 318200282 Rev B.
Technician checklist
On the filter circuit board, at the main incoming terminals, compare the house voltage reading between X1/X2 and between X4/X5 with the sheet’s 240 volts.
Jumpers X1 to X2 and X4 to X5 are examined.
The wire on X6 is the chassis ground.
When the supply voltage turns out proper, the filter circuit board is swapped.
Because these checks touch live supply connections, leave them to service.
Model compatibility: Frigidaire reuses codes across series and model years, so 35/75 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
Codes 35 and 75 both mean AC input voltage is too low at the induction housing assembly.
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.
