OTR Thermostat

[Jcparmley]

Hello All

I have a MCI 102c3 that I am converting.  I am just starting my conversion.  I removed the stainless registers at the floor.  After removing the registers I started the bus to move it and I noticed the thermostat on the dash read -40.  I think I might have removed the cabin temp sensor.  Can someone advise me as to where this sensor is or how to replace it.  Thanks

mine was on the driver side at the rear drive tires above the floor near the cold air return vents

Do you know what it looked like or do you know where i can get a new sensor?  Thanks

Does anyone know what this sensor is or what it might look like?  I found what I believe to be the wire for the cabin thermostat but not the sensor itself.  Please help me figure this out.  THanks

The sensor in an old MC8 had 4 wires attached to it, mounted in the air flow, inside the piping... oh geez... somewhere... maybe a piece of panel came off to expose it?

Long time ago since I had to think about it.

Isn't it in Da Book???

The book shows the sensor but dosen't show the thermal coupler in the vent.  Nor does it show the part number or which wires to wire in a new thermal coupler.  The book is basically useless in regards to how the thermostat gets it's single.

Mine had a miltery spec style connector, the ones with a screw down collar to lock the plug in place.  Was about half back on the driver side near the floor. 1994 MC-12

Ah... it was a Carrier system...

I've always wondered if there was an obscure separate vendor manual back then...

I have the sensor that broke off but it dosen't have a number on it.  Does your book have a part number for the thermal coupler?  Thanks

My books are all packed up and remote to my location.

Anyone else have the book or a part number?

You can download parts and service manuals from mci now. I can't remember exactly where but I believe if you go to mcicoach.com tgere is a link at the top of the page that will take you to support documents or manuals or something like that, then select your series etc. Etc.

Does anyone have any idea where I can find a replacement temp probe?  My parts manual dosen't have the part listed.  It's the little probe that goes in the drivers side stainless duct.  THe one that tells the thermostat the ambient temp.  Any help would be greatly appreciated.  Even if you have a manual that contains a part number that would be great.  Or a idea of how to retrofit some other type of probe.  Thanks

Hi Buswarrior

What would I call the "sensor probe" in the intake duct if I was to do a search on mcicoach.com?  Thanks

Perfect timing, for a brief moment, I am where the books are!

"Sensing unit - coach temperature"
Fwiw, the MC8 part number was 16B-10-33 and is listed in the "heating and air conditioning" section 16 of the parts manual, under "miscellaneous valves, switches, heat and A/C control components"

Just to get some of the wording familiar.
