You did not indicate the year or size of the mobile home, but, having lived in several in cold Michigan, here are some things.
Be sure all the windows are well sealed.
At first, I used to put a strong clear plastic sheet over the insides, and tape these in place.
Later, I bought foam insulation board at a lumber yard and cut pieces to fin the window openings, and taped them in.
When it is really cold, feel the walls, the floor, and the ceiling.
If you find cold to the touch, you are losing heat there.
If your floors are cold, put insulating panels and skirting around the bottom of the trailer.
If your extreme cold lasts for months, some people consider putting a small electric heater under the trailer that is temperature controlled.
Some people do a "roof-over" by setting poles or posts alongside the trailer and adding an additional roof above the trailer.
That step would enable you to add insulation above the top if your ceiling is cold.
God bless your efforts.

How many degrees before it reaches desired temp, does it shut off? A thermostat is designed to shut the furnace off a couple/ few degrees before it reaches set temp. It has what is called a heat anticipater, which shuts the burner down, and lets the blower use the remaining heat from the heat exchanger to bring it up to desired temp making it more efficient. If it is more than a few degrees, replace the thermostat. You can jump out the red and white wires to confirm the faulty thermostat. If by doing this, the furnace never shuts down, until you separate the red and white wires. That confirms a faulty thermostat. Hope this helps someone.

These are not designed to operate without a fan and doing so will cause the unit to overheat... There are 5 screws and a cover plate inside the rear of the unit. The fan can be easily removed then

A lot of units have a switch by the blower unit. It switches left or right. One way is automatic running from your thermostat and the other stay running...You can alway turn the blower off from your main breaker box..But that want fix the problem...If I had to guess..You have a small wire loose or disconnected in your thermostat...Take the cover off and look for small wires.. Sometimes these wires get broke moving the settings up and down...Find the lose wire and reconnect...You can replace the thermostat but you will still have to connect the wires to the new one...I have seen people with weed eaters cut a outside wire by the units that caused the blowers and units stay on...Hoor this helps

I had the exact same issue and replaced the control circuit board, igniter, flame sensor, and thermostat just to discover the real problem was a rusted out Roof Jack. (The exhaust pipe that goes through the roof. The inner fresh air pipe was rotted out so the furnace was sucking exhaust gases in which would not support combustion. Have your's checked.

It sounds like the fan is not functioning. With the breaker, SSU, and/or power off check the wiring, tighten any loose wiring, and make sure nothing is blocking the fan from spinning. Check to see if it will spin by hand, if there is access. If it does, and you have power, then the fan motor may need to be replaced.

Does this help? Let us know.
