We had our first freeze in Dallas last night. Woke up this morning to water pouring out of the unitherm governor port on the rp2100 while the system was cycling for freeze guard. I found the plug and the thermostat (which looks super rusted and gunked up) on the ground. Turned everything off and went into work.
- Why did the UG blow out? (Freeze guard was on, and I had the pool running all night.)
- Is the fix simple as replacing the UG and the cap?
I haven't used this heater in a couple years. It worked when we moved into the house, but a year later stopped heating. Just never got around to having it fixed. When turned on, you can hear the ignition firing and smell gas, but never seems to light. Are these problems related?
