First off I would like to thank Larry, Paul, Steve, The Daring Dufas and
That One for taking the time to help me with my problem. I decided for now
take Larry's advice and just turn the unit on because with the hot weather
the heater wouldn't be needed. I did and it works just fine, I guess I'll
put off the repair until the fall when it's a little cooler down here in
Tampa.
I did discover that I had the parts list for the unit all the time, it came
with the units documentation and the sump heater (part # HTR1298) is the
cigar shaped type. The settings of the thermostat that controls the heater
(part # THT0811) has settings that I would not have expected, closed at 73
and open at 105. I would have thought they would have been much lower but
they are what they are and I'll probably replace it also. If removing the
original sump heater proves to be more than I can handle I may consider one
of the aftermarket wrap around type heaters, it may be easier to install.
Thanks again
