This section covers removal and replacement of the thermistor. For a thermistor check
procedure, see "IV.E. Thermistor Check."
CAUTION
1. The thermistor is fragile; handle very carefully.
2. Always use the recommended sealant (high thermal conductive type), Model
KE4560RTV manufactured by SHINETSU SILICONE, Part Code 60Y000-11,
or Part Code 4A0683-01 or equivalent.
3. Always use the recommended foam insulation (non-absorbent type) or
equivalent.
