Furnace refuses to cycle off even when room is 20 degrees warmer than setting

Do you know how to access your furnace wiring ? What make/model furnace?

New thermastat Air won.t turn on at all or if it does it only stays on for a second and then goes off and won't come back on.

What model is the hvac unit that it is hooked to? There is a high possibility that the wires are not hooked up right. You should check the connections at the hvac and see if they are color coded and wired right.

Replacing a duotherm 3105058 thermostat

I was replacing a DUO-Therm 3105058 Rev A. very old Thermostat in a Coachman RV with 3106995.032 from Amazon. After looking all the information on the directions it was clear I would have to play a hit or miss on some of the wiring. Instead of using the same coding, such as RC, RH, G, Yellow and such. they used the function and I had to guess at some.
Here is the wiring I found worked:
There are 6 wires. One set of two wires (white On the W & red on the RH) and the set of 4 (yellow On the Y, green on the G, red on the RC and blue on the H). So to keep it simple the red on the RH went to the +7.5. The White on the W went to the FUR. HS/HP not used. the Yellow from the Y went on the cool. The green on the G went to the fan. The red on RC went to GND. and the Blue on H went to Hi fan.
So red (RH) of the 2 wire goes to +7.5
White (W) of the 2 wire goes to FUR.
Yellow (Y) to cool
Green (G) to fan
Orange or red from the RC lug goes to GND
Blue (H) goes to Hi Fan
