It could be a dirty connection(s). Is the fan original? Could be failing.

The thermal sensor may be fine. On my 182A there is a little metal
retainer that screws to the fin holding the sensor in place against
the fin. I *think* the 182B is the same. If needed, you should be able
to reshape the retainer so sensor is held to fin. Also, adding a
little thermal paste between sensor and fin might help.

Cheers,

Neil.
