Temperature sensor resistance
The approximate resistance of a temperature sensor is:
R = 100 + (.35  t)
Where R is resistance in ohms and t is sensor temperature in °C.

Ceramic and glass fuses
There are two sets of fuses on the AC power board:
 Two ceramic fuses protect the board from the oven heating
circuit (F3, F4)
 Two glass fuses protect the board from the main supply (F1,
F2)
See the table below for the part numbers. When replacing both
the glass and ceramic fuse types, always replace them in pairs.
