Cool Thermostat or A/C?

My trailer has a Coleman Mach 7330F3852 Thermostat. There is a slide-button on the lower right corner that lets you select the fan setting and speed, i.e., Auto (Hi or Lo), or manual Hi or Lo...(with manual settings the fan never goes off).

Last night the Auto settings stopped working, but the manual settings still do. I pulled the front off the thermostat and the only fuse present is connected to the slide-button on the lower left corner, which is used to select Cool, Fan Only, Off, Heat; and this button is working correctly.

I suspect the slide-button for the fan settings is broken, but before spending the money on a new one, wondered if someone else experienced this and how you eventually fixed it.

I'm surprised you've lived with that analog slider thing so long. First mod many of us do is to get rid of that thing and replace it with a digital of some kind. If I were you, I'd replace it with a digital and not look back. Here's a direct replacement:

8330 3862 Coleman RV Wall Thermostat for Heat Cool Control

This one is $44 but I think you can find them cheaper.

Thanks rockfordroo! Reviews on the one you mentioned was a direct replacement look good, so I'll probably go that way. Appreciate your taking the time to help me out.

That's a good unit, but you can replace it with a digital Honeywell also. Actually any thermostat that will control a millivolt system.

We'll be more than glad to help you figure out the wiring if you go with something other than the Coleman unit.

Bill: If you want to go with a Honeywell, see here (post #2) for what I did. I have a wiring diagram attached for a ColemanMach to the Honeywell.

Digital thermostat

The Honeywell I used does not have fan speed control, so you either have to pick a speed or install a SPDT switch as I did. I mounted a mini-switch in mine, as you can see, but you could mount an RV-type rocker switch in the wall next to the t-stat. I may end up doing that, as the DW has problems with the tiny little switch. If you want to go that route from the start, I'd recommend a JR Products model # 12625, ON-ON switch.
