Programmable thermostats are currently off, however the blower is running. Doesn't run all day but most of the time

Exact model number of furnace and brand

Exact model number of thermostat and brand.

Unless we know exactly what equipment you are dealing with it is just a guessing game.

Rheem Classic 90 Plus

Looks like this is the serial number of the evaporater coil,, not the furnace

Brand and model listed, is that enough?

NO,, beside the numbers it says Ser #
When I looked these numbers it says its for a evaporater coil

The numbers needed are inside the furnace

Well previous poster asked for brand and model. Not sure what relevance the serial number has. Seems too much of a hassle to locate
