Nutone HD80NT Exhaust Fan Incorrectly Rated for Continuous Operation
I bought this exhaust fan from Home Depot at a price of $94 plus tax. It wasn’t the most expensive exhaust fan they had but there were a whole boatload a lot cheaper. I bought this was expressly because it was the only one I found that stated clearly on the box that it was rated for continuous operation. NOT!
From the Nutone Web Site Model HD80NT 80 CFM Heavy Duty Fan
• 80 CFM, 2.5 Sones
• Totally enclosed motor design for continuous operation.
After installing it which was a total pain as it was replacing an existing fan but that is another whole story, it ran for a whopping three days before is started making straining noises. I turned it off and let it sit for 8 hours and turned it back on, it ran for a day and started making noises again. I solved the problem by adding an Intermatic time switch which turns the fan on for 8 hours a day. If I had to buy the Intermatic it would have added an additional $45.00 to an already expensive fan. I happen to have a couple of Intermatics on the shelf so it wasn’t an issue except for the fact that Nutone claimed the fan was rated for continuous operation. Once again, false advertising and inferior products claims another victim.
