Most air cons now have temperature sensors all over the machine. When it reaches temp on heat cycle, the machine usually shuts down both indoor and outdoor units but the indoor unit will keep running for a few minutes with the fan on only to cool the indoor unit down. This prevents the unit reading the wrong temperature. It stops the sensor(s) reading the heat from the indoor unit rather than the heat in the air in the room.

Motor shuts down when reaching normal operation temp

Sounds like the mass air flow sensor or the air intake temperature sensor. Sometimes just wiping out the throttle body/air intake can make all the difference

Good Luck and Happy Motoring

I have a 1998 Ford Expedition 5.4l, engine has an intermitent miss-fire and hesitation after reaching operating temperture. I have no CEL or stored codes. This problem is much worse when the A/C is on. I...

Your good
I would still remember, that all ford COP Coils have issues,from 1998 thru today
The Coolant Temp Sensor, should put it into closed loop, after it warms up---then the O2 Sensors can do their thing. That's one item
O2 Sensors slow to swing--maybe,need to test
Converter partially blocked-a bit of a stretch, but don't rule out.
I would buy one new coil, and walk it down from cyl to cyl,tough on that engine,but I put my money there

Refrigerator keeps freezing even when i turn the temp knob to 1 or low?

The thermostat or temp control may be bad causing the system to run non-stop.

There could also be a problem within the refrigerant cycle. Maybe a low charge, or no/faulty defrost cycle.

If the unit pulls to temp and continues to pull lower until it freezes, then the problem is most likely the temp control. If it will not pull to temp and the evaporator freezes up, then you may have a refrigerant charge issue.

Remember that the temp control on that unit is a coil temp sensor. It does not measure the air temp but rather the temp of the evaporator coil. So a larger air temp swing is expected, but the system should not be freezing up at all.

Blower fan runs at one speed - very low

There is a sensor on the indoor coil that needs to reach a certain temp before the fan speed will increase. Sounds like the unit is undercharged if the sensor isn't reaching the temp it needs to.
