I have a Rheem Model RHSA-HM3617JA and need a wiring schematic so I can wire in the thermostat

moved yah from cars to HOME HVAC
the maker RHEEM has a web site.
and has full documentation on that, and more.
go there get it and see it.
if using non RHEEM stat , that takes a book on that stat too.
and is not too hard to figure out.

This site has the manual and wiring diagram for the Therm-o-Disc thermostat: https://www.ferguson.com/product/rheem-fury-40-gal-tall-45kw-2-element-residential-electric-water-heater-r82v402522951/_/R-2822886 . The current link to the manual is https://api.ferguson.com/dar-step-service/Query?ASSET_ID=1304254&USE_TYPE=PARTS&PRODUCT_ID=2822886 .

I hope this helps.

typically the compatible heater models are all labaled, different sizes, on the data plate of the air handler.

Sounds like a relay inside the air handler is stuck 'closed'...

1) Copy following links for wiring upper thermostat:

http://waterheatertimer.org/How-to-wire-water-heater-thermostats.html

2) Thermostat must sit flat against tank wall to read correct temperature, and entire opening must be covered with insulation so cool room temperature will not interfere with temperature reading.
Be sure to put cover back on side of tank for electrical safety, and to prevent any possible fire caused by melted parts and overheating.

3) Tighten wires very tight under screw plate, and make sure only copper wire is used, and all wires under plate are same gauge, do not mix stranded wire and solid wire or stranded will become loose.
Only copper under the screw plate and cut back insulation so no insulation gets under screw plate.

I can't identify that model number, and Rheem does not show that model:

if you have 2 wire at thermostat Terminals at furnace that the thermostat wire attach to should be R & W if your new thermostat has R & W terminals is should work, an easy thing to remember is the red wire on R the white wire on W. If 4 wire at thermostat at furnace green on G, Blue on Y, red on R,and white on W same at thermostat If these do not match find a thermostat with these terminals

Must be a transformer gone out.

Have you hard wired your fan motor to verify that the motor and or the capacitor are good? If you do a continuity test of the motor leads(with electricity off of course) you can see if the motor has open or grounded windings.
