What most likely happened is 1 fan quit and you didn't notice it until the 2nd one died and now you have neither fan operating. This is not so unusual as both fans have the same run-time so they wear evenly. When the brushes inside get too short they don't make good contact (less spring pressure) so the motor stops. The vibration from hitting the housing can sometimes get the motor to go again for a short time but the sad truth is the motors need to be taken apart, cleaned, lubricated and new brushes installed. For further improvement for the fans I recommend either a Fanzilla or some other upgrade over the fan fail relay or the bypass wire. Also change the circuit breaker. Make sure all of the connections are clean and tight, this is a high current circuit operating at near the design limits of the wiring and connectors. A Fanzilla can tell you if 1 or both fans are not working so you won't get surprised again. This is what the fan fail relay was SUPPOSED to do and the bypass wire cannot.
