OK, I've got two B2 Eber. gas heaters here, and the thermoswitch/quarz sensor rods are NOT coming out without shearing the top off the inner chamber threaded connection, (in fact I've already done this with one, so I suspect the heater is instant junk). They are SO delicate here, yet it requires their removal to service the switch. VERY poor design. After 30 yrs, the nuts are so siezed on I would say your are NOT going to get them seperated from the inner chamber threaded male fitting. If anyone knows who can service and hopefully repair my little learning experience I would appreciate it.
Thanks,
Courtney
