It seems that when the temp drops below 20 my lights flicker & dim, the
microwave won't run & the TV picture shrinks. This occurs when all the
big load devices are off so I believe it's power company related. Any
thoughts on what would cause this?

This is not something one would normally expect to find and you should
contact your utility provider directly. Even if there were a large
number of electrically heated homes in your immediate area, any drop
in service voltage would not be that obvious, nor disruptive.

Have you talked to your next-door neighbours and, if so, do they also
experience this problem? Roughly how many homes are served by your
distribution transformer?

Cheers,
Paul

Thats a bad sign , you should not use appliences with that situation .

If you have a voltmeter you may be able to get a voltage reading .

Contact the power company as soon as possible.

Do you have a heat pump? At low temperatures they have a large resistance
heater that comes on.

No, we have propane heat.
