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.

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

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

We/ knowone can look up the specs on your equipment to try and help you without the MODEL number, notice (model number) not serial number,they are different
There are hundreds of Rheem Classic 90 Plus,furnaces,and they change from year to year,If you want free help,you have to give a little, unless you don`t need the help
