What RBM asked... :)
But, yes there is a switch, but an automatic switch is called a relay.
The click makes it sound as though the thermostat is functioning but
either the contacts are burnt and not closing (doesn't seem right or it
seems unlikely it would heat originally) or there's a
temperature-related failure. That it appears to come on when cold but
not again after warm makes me think of the thermostat and/or relay
controls being mounted on a circuit board that has a cracked trace that
opens when warms up then conducts again when cools down completely.
Just a WAG given the symptom and no other info...
