Beeping Fridge Fix - By Jim Fielder

If the opening isn't too wide you should be able to use silicone. You can buy it in smaller tubes, you don't need a caulk gun.

Are you suggesting silicone sealer inside the switch unit or spray? Also I remember in deep water crossings when I had a macho 4x4 I sprayed the ignition wires with WD-40 to dry out the wires. Would this work in the frig?

I have the same issue with the Dometic refridgerator, after 2 trips to the dealer in which case they could not get it to beep for them and much frustration on my part I started research on the problem. My first fix was to just unplug the switch which solves the problem but that disables the light, reading the tips on the forum I tried to dry it out and put some dielectric grease on the circuit board because I could not find anyway to take apart the switch witch might ruin it, this worked for a while but it started again when we ran into some humid weather so now I am trying forest rivers fix which is to pull back the tape which covers the wire going to the switch and silicone the space around the wire to seal out warm air coming in from behind the fridge and if that don't work I will just leave it unplugged. One more thing I found was because it is a door open alarm that the upper tray in the door has two positions and when its in its outmost position it seams to keep the door from closing all the way resulting with an alarm. Hope this helps someone and Good Luck.

I am not a big fan of silicone sealant and would be very careful in using silicone around electrical connections. Do not use any of the silicone with an acid cure (acetic acid, smells like vinegar). Use a neutral cure, non-corrosive silicones if you have to. I did not have any beeping with my refrigerator, but I did not want to have the problem while on the road, so I coated the led board with Plasti Dip Liquid Tape, as it says in there brochure, Provides excellent protection from acid, alkaline, and abrasion, Seals out moisture and salt , Strongest dielectric protection on the market, Protects electrical connections on wires, cables, alarms, electronics, Will not harden, unravel or become brittle in extreme weather conditions. Other good one are Performix, Electrical Liquid Tape and Star brite Liquid Electrical Tape (this one comes in clear)

Yes, Liquid Tape is flammable but only in its liquid state! If the tape is not fully dried it is still flammable.

From the manufacture; always follow the directions on the label.

Surface must be clean and dry. For best results avoid direct sunlight, high humidity or breezy conditions. Using brush cap, stir gently and thoroughly before each use. Always disconnect power before making repairs allowing Liquid Tape to thoroughly dry before restoring power. Follow local electrical codes.
1.Liquid Tape can be used over existing connections using connectors, solder tape and shrink tube.
2.Apply Liquid Tape to connection or repair area. Make sure to completely coat repair for air- and water-tight seal.
3.Allow 10 minutes minimum between coats. A minimum of two coats is recommended.
4.Allow 4 hours minimum dry time before use.
