The operation and repair of the original Nutone exhaust fans has come up a few times in the past few months. While the original fans aren't very powerful, they did \u2014 and can \u2014 work and potentially alleviate more drastic measures in venting your Eichler kitchen or bathrooms. Like anything that's nearly 70 years old, parts wear out and could use a refresh. Fortunately, in the word of Eichlers, the original parts were so simple that repair \u2014 versus replacement \u2014 is often possible.<\/p>\n

First, it's important to think about air movement and how that works: motor speed, fan size, fan blade shape all come into play, but in realistic terms, you're only going to pull so much air with an 8in fan blade within a 9in tube. So, keep your expectations realistic. If you do need industrial-level exhaust, you might be better off looking to other systems.<\/p>\n

\n

\u2026 when living in a 70 year old house, you should expect to get your hands dirty every now and again \u2014 it\u2019s part of the adventure.<\/em><\/span><\/strong><\/span><\/p>\n<\/blockquote>\n

<\/p>\n

 <\/p>\n

<\/a>Otherwise, the fan mechanism is simple: a small AC motor with a 2-prong cord attached to an 8in fan blade. The blade was originally aluminum (and you can re-use that one), or get a new plastic one. I'll post links to products below \u2014 some of which may\/may not be available when you order. All are AMZ links … sorry.<\/p>\n

Installation<\/strong><\/span>:<\/span><\/p>\n

Installation is fairly simple: Remove the old fan \u2014 replace with new one. Below are some pics of our own fan that's been in operation for a few years. It took 87 seconds to remove the grill, unplug the fan, unclip the motor, remove, and photograph. It's super simple. If I recall, when fitting the new motor to the harp, i had to enlarge the holes for the new studs to fit well, but it wasn't complex. The original harp is important as it is the thing that hold the grill to the ceiling, so be kind to this part \u2014 you could re-create, but …<\/p>\n

The fan motor is attached to a metal bar (often called a "harp") with two flip-clips \u2014 it's easy to remove as long as the clips aren't summed up. If they're gummed up with years of kitchen grease, take some time to clean first. I like a mixture of d-limonene<\/a>, "purple" degreaser<\/a>, and water (1:2:20 mixture) \u2014 the d-limonene and degreaser make a good grease-cutting suspension solution that is easily dispersed via a spray bottle (shake first \u2014 it will look like milk). You can also use this mixture to clean up the housing and fan blade, too \u2014 the cleaner and slicker the parts, the smoother the air flow.<\/p>\n

Often, the hardest part is fitting the new fan to the harp and some muscle might be required to get everything to align, but you can make it work… I've kind of come to the realization that when living in a 70 year old house, you should expect to get your hands dirty every now and again \u2014 it\u2019s part of the adventure.<\/p>\n","protected":false},"excerpt":{"rendered":"
