Been using the furnace for almost 2 weeks and it is now moving substantially more warm air to all vents. The first night it stopped heating as I think
we hit thermal safety. In recent years motor, board and gas valve were replaced. RPM seems same on motor in both cases. Is there a flat on the
motor shaft for squirrel cage set screw or could my indoor blower wheel been slipping? Also can/should the motors be oiled? Thanks

Check to make sure you have an unobstructed path for the return air or make
up air. Lack of free flowing make up air can cause the furnace to overload.
Make sure the cabinet the furnace is in is not too air tight and nothing is
laying on the return air grill in furnace body.

Both outside and inside airflow has increased. Maybe the motor was tight from lack of use? Was on shore power in all cases.

What is the diameter of your ducting?

I think the threads got crossed up. My Solare is long gone and running a Suburban. The only remnats are abandoned Solare vents on the side next to
the Suburban.

The stock solaire ducting is smaller than the recommended ducting for the
suburban. Iirc the larger original solaire ducts in my coach were 3.5 inch
and 2.5 inch. The suburban installation manual stated 4" as minimum. I
removed the holey mouse house infested smaller ductwork and replaced it
with all 4" and deleted the smaller bath module only duct and aux pusher
fan. The suburban model I installed is the SF-30. I don't know if you have
the installation manual for the model you have but there are a few very
useful bits of information in it as far as air movement and duct sizing.
Your mention of the furnace shutting off and your thoughts that the thermal
switch was the reason made me recall my installation and the ducting
requirements of my furnace. One of the reasons they gave for the duct
requirement was prevention of over heating of the furnace.
