Found no live going to toc`s or heater. Has its own
reversing timer attached to base of appliance. Heater
lead goes to rev timer. Lives go into timer ok.
Can I assume this is the problem. Not seen these rev
timer machines before.
Yes Laurence, the reverse timer switches the heaters off during each ‘pause’ period. So most likely the reverse timer is the source of the problem? 😉
