Question about Heating & Cooling
I had to replace both hi limit sensors in mine. The sockets that they fit into has a plug inside that corrodes and allows clorine water to escape. I had to put the plugs in with auto gasket sealant around threads only. This solution helps but the sensors should be inspected now and then for corrosion. Lithium grease on electrical conectors on the bottom of sensor helps to. This area is attacked by corrosion big time along with top. (winterizing) On low pressure switch inside the heater the copper tube must be undone on switch or undrained clorine will clog up lower tube with corrosion. This blocks low pressure switch from working. Then you have to cut small piece off and redo the tubing. Been there done that. For the most part the Laars hasnt been a bad pool heater but the hi limit sensors along with the plugs could have been engineered better. Good luck and watch the ph...StLouis
