Mystery Switch

[ALANU33]

i have an unlabeled mystery switch in my 2006 coachmen. i think it might be a tank heater switch. My model is suppose to have it. Its not labeled and the switch doesn't illuminate. I replaced the switch thinking the light was burnt out but it still doesn't light up. I have the switch out in the picture for testing. I can trace the wires to where they go, but i am hoping someone has the same panel and can save me the trouble.

Thanks
Alan

It may help if you listed the model of your unit along with the brand and year.

I don't know why it's such a problem for the mfg's to label the switches, but there are a vast amount of unlabeled switches out there and a good number of them are for tank heaters.

We have a 2007 Coachmen Freelander 2600SO and our panel is similar to yours and we have the same unlabeled switch. We were told it's for the heaters on the black and gray water tanks.

Thank you for confirming.
I assumed that's what it had to be for.

Heated tank pads usually only work below 40 degrees or so.

If all the other switches are labeled (including water heater switches for propane or electric) then it’s probably for tank pads. If you’ve got a digital meter and can clip on to somewhere to monitor the house 12 volts, you should see a drop in voltage when you turn the switch on, because heaters of any kind usually draw a fair current.
