Hancoman Posted May 17, 2022 Share Posted May 17, 2022 Hello Recently on a trip I turned my aqua hot on for heat ,the fan under the bedroom vanity made a noise like someone stuck a pencil in the blades and then went out. I am home now and pulled up the shelf in the vanity to expose the fans. My question is is it usual for both fans to go out at the same time? Should I be looking for a blown fuse? Everything works fine as far as the Aqua Hot goes the heat exchanger gets hot just no fans working. Thanks Tom. 2001 Executive Link to comment Share on other sites More sharing options...
Ivan K Posted May 17, 2022 Share Posted May 17, 2022 I suspect your AH is the same as ours, 100-02s. If so, there are zone fan relays and fuses under the cover where usual maintenance is done. Since the fans should be wired in parallel at the exchanger, double fan failure does not sound likely. I would go after a burnt fan fuse inside the box.but it is easy to check for voltage at the fans first, while you have them in sight. Link to comment Share on other sites More sharing options...
vito.a Posted May 17, 2022 Share Posted May 17, 2022 Get out your voltmeter and check for voltage at the fans. It's probably not there so then you need to remove the metal enclosure and crawl into the basement compartment to find the fuse. Best of luck!

Donflem Posted May 17, 2022 Share Posted May 17, 2022 I just had this happen on my inverter both fans went out. I got lucky just replaced the fans and so far so good. Don Link to comment Share on other sites More sharing options...
