The model # is: SA-HT940
The machine operates within normal parameters with one exception; neither of the two cooling fans work.
I have ceased using the machine since this problem began although it did work fine for a time before the discovery was made.
I want to know if there are any suggestions other than seeking a repairman as there are none in the area. I am also somewhat reluctant to simply order new fans unless all other options have been exhausted so that I do not do so and find out that the problem lies elsewhere. Thank you for your time and consideration.

It would probably be unlikely that both fans failed. More likely the circuit that triggers and powers them…
Are you sure they’re not thermally activated and only come on when they need to? That’s a common feature to keep the fans quiet when the system is playing at a lower volume and not producing too much heat. It also makes the cooling system more complex and likely to fail over time…
If that’s not it… I had a similar problem with the fan circuit on an old receiver. I powered the fan with a 6 or 9 volt “wall wart” I had laying around (I forget the exact voltage) and the fan operated at an acceptable speed. I plugged the “wall wart” into the switched outlet on the receiver so the fan only came on when the receiver was on. Good as new…
Run a hot wire directly to each fan from a dc power supply or “wall wart” to test if the fans will work with proper power. If not,replace the fans. If they do work,the circuit that powers them is not getting warm enough to warrant use or is defective. The wall wart use seems a nice workaround if you don’t want to pay/wait for repairs.
