What’s this switch for?

[mark49]

I’ve only just noticed this switch on a thetford SES fridge. Can anyone let me know what it’s for and the position it should be in. I think it’s been in the off position for as long as I’ve used it but can’t be sure.
Thanks

it is probably a heater element in the freezer bottom to stop things freezing in place

Looks like an on off switch for some thing possibly a fridge fan

The fridge in one of our vans had a switch to heat the door frame to stop condensation.

Found on the net...

If it's a N145 or N150 fridge - it's the switch for the "divider heater", only found on double-door fridges.

Quote from manual . ..
"By heating the metal plate between the freezer and the fridge cabinet, the divider heater prevents ice-forming when the freezer door is opened and also prevents the freezer door from freezing stuck to the metal breaker of the fridge. To save energy, the divider heater can be switched off. The switch can be found on the side of the control panel near the latch."

Don't leave it turned on when you are NOT on electric hook up. My last motorhome kept me busy for a happy half hour one day while I tracked down what was drawing such a load on the battery

Shouldn't that function be part of the SES or AES system? Ie, only on when on an EHU. Not sure why they'd rig it to flatten leisure batteries unless you manually switch it off. Seems a bit daft to me!
