Helpful Expert Reply:

Your Fantastic Vent model 8100ts doesn't have replacement parts available, so I recommend using a circuit tester like # PTW2993 to check for power functions. I reached out to the manufacturer and in addition to this, they said to check the circuit board. You may need to simply clean it and add some dielectric grease like # 11755 to help with electrical connection and keep dirt and moisture out. If there are scorch marks on the circuit board, then the board is fried and the entire unit will need replaced.

To replace the unit, I recommend the Fan-Tastic Vent Roof Vent w/ 12V Fan and Thermostat - Powered Lift # FV803350
