Dielectric sealant

gogo97gti

I have a indoor/outdoor thermometer, and the sensor that runs outside became disconnected. I soldered the leads back on, but the sensor was embedded in some sort of clear sealant inside of a plastic casing. I tried regular silicone caulk, but that caused the temp to spike, so that's a no go. I'm imagining I need some sort of special dielectric sealant, but I have no idea what or where to get it. Any help would be appreciated!

did the temp stabilize once the caulk finished curing?

stick it under the housing where your control wiring on your hp is to protect it from weather,should be fine

Maybe try some epoxy . kerry

Didn't let it cure. It was obvious that the caulk was having some sort of insulating effect that made the temp go up.

I want to make sure the stuff I use is right because there's no way I'll be able to dig it back out of dried epoxy if it doesn't work. I want to try to avoid having to buy another sensor.

I believe that the main reason for the sealant was for moisture protection. The stuff that I dug it out of originally was clear.

mounting it under there with the contactor and other stuff should protect it from moisture,thats where i mount outdoor stats anyway
