Most likley this is caused by a pressure switch dropping out then making again after the pressure drops off. Try cleaning your coil on the outside on the roof as most likley it is a high pressure switch causing this problem.

Don't really understand what you mean by roof top duct unit .if it's a roof top unit and water is leaking down your vent then you have a clogged drain line .

Maybe unit is already satisfied. For unit to run in heat temperature set point must be above room temperature

You need to get a different thermostat.you can change an analog thermostat to digital, but you have to replace the motherboard with a digital compliant one. You can't just change the thermostat. Your best bet is to put back the old thermostat or upgrade to a different compatable thermostat

Should be a fuse somewhere for that blower

Go to your heater and locate the circuit board inside. There is a 3 amp fuse that protects the board and it is a regular auto fuse and isn't made for any surges in the system. When you turned your generator on with the system on, chances are you surged the system and that fuse went. Breakers allow for surges where fuses don't

Shut it off and get it checked. Ammonia is dangerous as I am sure you are aware. Ammonia smell is an indication of a leaking cooling unit. Time for a new fridge. Sorry.

Your thermostat is no good. Depending on the age of the unit, you might be able to replace it. Pull the cover off the bottom of the unit to expose the thermostat. If it is an older unit, you'll have a copper capillary tube that is connected to the sealed system and you'll need to take it to an RV repair shop to have it replaced because it is a mechanical t-stat and you'll need to break into the sealed system to replace it. If it's a never unit and you have wires on it, It's a matter of pulling it out and finding a replacement

Most thermostats operate this way. Instead of dropping the voltage a thermostat opens the circuit when the set temperature is reached, after which it closes again to redo the cycle again. The principle can be based on heat, time or pressure. The animation, if the GIF runs, shows the basic principle for a thermostat switch in a heater/geyser, but can be modified to operate via a pressure diaphragm as used in ovens and fridge compressor relays. Strip heats/opens then closes.

If your thermostat no longer controls your furnace possibly could be the control board in the furnace or a shorted fan relay.
