Other Classic 90 Reviews
Comments on the HVAC-Talk message boards and heating contractor sites are generally mixed regarding the performance and repair of the Rheem furnace:
- One author at the HVAC-Talk forums claims that the Rheem fan doesn't work consistently, due to weak controls, but when the furnace does work, it produces a good amount of heat.
- Another person claimed that Rheem is inefficient and does not always perform properly. This forum participant, like the other poster, felt that when Rheems does work, the quality of performance is noticeable.
- A third person insists that Rheems no longer provides replacement parts, making the correct parts hard to find without an effort. However, Rheem diagrams provide clear direction for installation, so when these schematics are followed, effective installation and motor performance are assured.

Amazingly enough after spending quite a bit of time searching through Rheem documentation and searching online I haven't been able to clearly identify the location of the reset button. More than likely it is on or near the control panel attached to the furnace, but hard to be sure at this point.
Before poking around I suggest calling either Rheem or a certified HVAC tech and asking either.
I also have to ask if there is a reason why you need to hit the reset button. If the furnace is not functioning properly it may be best to find the LED fault/error code display and see if there is a code flashing. Again, after going through Rheem documents and online there is not a lot of information, but I did find this description:
"In the lower panel, you'll notice a little round "window" that peers onto the control board. When the unit shuts down, there will be a little light flashing in the little window. This will be flashing a code, seperated by a pause, and then the code again. Count the number of flashes, and correspond that number with the error chart listed on the inside of the lower door."
So if you can ID the error code it will give a sense of the problem. More than likely you will need to call and HVAC tech to come and do a full diagnosis and to fix the problem.
The Classic 90 is available in different models which vary in efficiency and capacity.
