Is this a hard part to install? I would like to do it myself.
Answer Hello Janis,
This is not a hard part to install. You would unplug unit and take rear cover off control panel. Pull the knob off. Remove one wire at a time and connect to new part to ensure proper wiring.
What does this switch control? When it is filling up with water it seems like it just keeps filling and leaks out on floor.
Answer Hello Dave. The switch 134409000 is for the temperature. If the pressure switch 134680100 is bad, it will cause the water to overflow. If you have to turn the water off at the shut off, you will need to replace the water valve 134190200. Hope this helps.
