Issues with Tedco 3-Way Fridge on Electricity

[. Leigh .]

So, I've been living in the above Boler since the start of September and fixing some little issues along the way.

Running the fridge on electricity seems to be an issue. I'm wondering if anyone has any advice on troubleshooting this issue?

The model is a Tedco 202TW. It seems to run fine on LP. When I switch it over to AC or DC there is nothing.

Here are some pictures of the back of it:





So, a few questions, does the switch for switching over to electricity in the above images look normal? I'm just wondering why there is a hole in the switch and if maybe something else was supposed to be there?

When the fridge is switched over to DC how soon afterwards should I start feeling warmth from the heating element? Should there be any noise?

What kind of power draw should I expect from the Fridge and would the fridge draw power even if the heating element wasn't working?

I appreciate any knowledge you guys have

DC is VERY inefficient and will drain your battery in short order. Some don't have DC.

I don't have your make/model frig but it looks to me like there should be a tab on the right like the one on he left.
Absorption refrigerators are SLOW and do not make noise.
Do you have or can you find a copy of the owners manual?

A typical small evaporative refrigerator such as yours uses about a 100 watt heating element for electric operation. Dometics have two separate elements, one for each voltage.
Have you looked on-line for a manual/schematic?

Here is a manual and a basic hand-drawn schematic that shows two heating element.

Zooming in on the manual Bob found on page 3 it looks like the sliding selector lever
is a broken on the right side as you suspect. It looks like a 3 position DC AC Off switch behind it is broken.
