Norcold 120 volt heating element

Glad you just had a poor electrical connection and are cooling again on shore power.

I'll have to try the penetrating fluids when it is not being used in season. And, I'll check for a second available slot.

I read 39.5 ohms and2.9 amps. Sure seems ok to me.

I've had this problem about once a year and cleaning and making sure the fuse holder clips are tight has always fixed the problem. The fuse was blowing in about 6 seconds. After a couple cleanings and checking for tightness and 3 fuses, I cleaned all connections with a metal polish (Wenol); installed a new fuse; all is fine for now.

I would still like to work on getting the heating element loosened for future replacement, if ever needed.

Thanks to all for all the good info and help.-- Mick

Mick be sure to read on Chris Bryant website. He has info and diagrams that I used to self teach myself about RV frigs when ours started to fail.

They are quite simple devices. We had to clean our electrical connections as Chris mentioned above.

Should be 48 ohms, 2.9 amps @ 120 volts, 300 watts.
Does the fuse blow violently, or just melt? These fuses do have a tendency to melt because of corroded fuse holders, but they can also have an intermittent short in the heater (short when it gets hot).

I use penetrating fluids- they burn off quickly without igniting on 120 volt power.

If the barrel holding the 120v element has rusted you will need penetrating fluids I expect. Just do not put any flame on it.

Our 6162 had an empty barrel since it does not have the 12v element being a two way frig so you could just use that one.

When we put in the new cooling unit from RVcoolingunit.com I bought a new 120 element and put it in the spare barrel and hot wired it. Now if I loose my circuit board, etc I can manually operate the frig by plugging the spare element into the 120 volt AC outlet under the back of the frig. If I do not want to mess with replacing the dead element I will just plug the new one directly to the board.

I do not have the Ohm's reading range at hand but google will get it for you.
