Ok, so this one is, of course, a use at your own risk document. I am not a professional electrician. Homewerks products totally blow and no one carries parts for them. I tried going to their website directly, but my relatively new fan was no longer listed and I could not get in touch with anyone there. I love using Repair Clinic to fix most of my other appliances, but even they don’t carry Homewerks parts. So do yourself a favor, and buy a name brand fan in the first place. If, however, like myself you find a Homewerks fan in your bathroom and the heater fan blows air, but there is no heat. You may follow the following steps to see if the problem is a simple issue like a Thermal Fuse. If the power sucks as hard in your neighborhood, as it does in mine (because you are hooked up to very dirty power from a totally corrupt, backward supplier like Puget Sound Energy, who is protected by even more corrupt politicians, so they never improve their quality of power or modernize in any useful way.) then you too may get to develop many more electrical troubleshooting skills than you ever imagined as their terrible power destroys modern electronics around your home. (Many of us are in this situation in the US and don’t even know it. That’s what happens with monopolies.) Of course while their terrible power causes irreparable damage to the environment they are running a green power campaign. Because being green these days is about putting up posters, and advertising, no actually doing anything significant…. Anyway, onto the repair.
- Turn off the breaker to the fan and confirm it is off. (If you don’t know how to do this, then please stay away from anything electrical until you do). Basic multi-meter skills are a must for any modern homeowner.
- The manual for the fan goes over removing the light cover, light, grill, and fan itself. You should do this.
- Using a Digital Multi-meter (Ok well any meter that has a continuity test (usually this setting looks like a wi-fi symbol, btw) test the thermal fuses to see if there is continuity. There are many YouTube videos on how to do a continuity test so I won’t go over that here. (FYI, it beeps if there is current traveling through the components).
- Replace the bad thermal fuse with a matching fuse. I ordered mine from Goodman’s via Amazon. The fuse itself will have its range marked on the side.
- Replace the fan in reverse order.
Note: Inspect all of the components. If your coil is obviously broken, then the problem also includes, or may just be, the heating coil itself.
Here is a helpful picture of the thermal fuse.
Personally, I did this repair because of how much of a pain in the ass it is to install most fans of this style, because the fan wasn’t that old to being with (see the “Homewerks stuff totally blows quote above), and mostly because this was a simple repair that should yield many more years of use out of the fan and cost me about $4 to do with shipping. I did not see any wiring issues, or anything else obvious, that should have caused this failure in the first place. So I think it was just a faulty fuse this time. You should always inspect your components when doing a repair like this. Sometimes the fuse is just bad, but more often, you have a larger issue causing it to fail.
