Dear Mr. Electrician: What is needful for a bathroom fan repair? The exhaust winnow in my bathroom obstructed working after making disturbance for several weeks. Does the entire bathroom sports fan housing need to be replaced?
Solvent: A successful bathroom fan repair begins with having the correct replacement parts. In many cases a residential bathroom sports fan motor can be easy replaced. NOTE: Some text links downstairs go to relevant products on Amazon, Ebay, or to my FREE Bath Fan Repair Book. As an Amazon Associate I earn from qualifying purchases.
Quite few bathroom fans were factory-made for a simple and double-quick initiation by the original installer. Consequently the parts replacement rear end atomic number 4 almost as simple.
The rooter motor to a higher place is held in place with two screws supporting the bracket (Bank note the pear shaped slots). The electrical energy is connected with a plug. The living accommodations is already grounded from the power supply, and so when the motor gets decorated firmly, ground continuity is maintained.
BATHROOM FAN MOTOR REPLACEMENT
The key to a successful lavatory fan motor replenishment is getting the correct refilling parts. Many bath fan replacement parts are in stock, just identifying the correct parts buns be a chore.
When your bath fan was manufactured, a model number was labelled inside of the housing or on the fan motor support bracket. Not the number on the motor itself, though that number is sometimes helpful and worth writing down. The lover model number may be stamped into the metal or on that point may be a label pasted wrong somewhere.
Before working on the sports fan, put a drop cloth dejected and break up a face mask and eye protection. Old bathroom fans sometimes have an abundance of dust and dander inside. Use a run when reaching up for the fan. Read my post about condom precautions.

When replacement the motor, always replace the fan sword. Wear't adjudicate to use the aging lover blade with a new motor. It is difficult to remove the old buff blades and they can get stained. Sometimes the bath fan motor replacement is sold as a kit with bracket, motor, and fan blade.
For those of you with a Nutone 696N B Unit bath run down fan, the factory has a switc kit available. The Nutone C350BN includes a motor, fan blade, and square bracket all gear up to be snapped into place.
Much Nutone and Broan model bathroom fans that were originally installed by the builder of your home have a retrofit bath fan climb kit available to change out the motor, lover blade, and grill spell the existing fan housing clay in come in. This is the easiest thing to set, and the manufacturer claims an improvement in noise and air movement. The kit is sometimes cheaper than buying the replacement parts.
The bath fan rise kit is a Nutone 690NT and can be old to replace motors and elevate single models of Broan and Nutone fans, but not all. Note that Broan has an identical upgrade kit out with the split up number 690 and a different color box. Nutone and Broan are the same company. They merged in concert many years ago.
UPDATE: I have read recently that the 690NT has been discontinued. The replacement for the 690NT is a Nutone Quickkit #QKN60 for 7.5″ x 7.25″ housings. I have non old this model, just downstairs are photos and verbal description of a Nutone 690NT tub winnow upgrade kit out facility.
I am guessing that the QKN60 will be a little scra easier to install as IT appears that no assembly is required. Unlike the 690NT, the Nutone QKN60 has the motor already attached to the bracket.
Information technology will probably take thirster to receive away the run and clean the active fan housing than it testament to actually install the new fan motor.
The Nutone QKN60 will only fit along the following model fan housings: Nutone 695 and 696N, Nautilus N671 and N688, and Broan 670, 671, 688, 689.
Sometimes I found that my most difficult challenge with a bathroom fan drive replacement was getting the grill back happening. It is usually because the bath fan housing was originally mounted too high above the finished ceiling rather of being hot flash pro re nata.
I surmised that the fresh bath fan installer did not know that forked wallboard or resilient channel was going to be installed. More close to this in my FREE bathroom fan repair leger.
The 2 mounting brackets and wrench that come inside of for each one Nutone 690NT Bathtub Fan Upgrade Kit. I lean all of the model fans that can repaired or updated using the Nutone 690NT kit in my book "Almost Everything You Indigence To Know To Repair A Toilet Sap Fan In Your Home".
The kit leave have instruction manual and a small pull in addition to a new drive, rooter blade, grill, and two mounting brackets. Basically you will be attaching the new motive onto the current proper size up bracket and putt information technology into the existing fan housing that is already in the ceiling. The motor is held in place on the angle bracket with two nuts that are provided with the wrench.
Thither is besides a spinnbar plastic strip that gets inserted into the housing to direct the airflow.
Concisely, you remove the existing motor and the attached fan blade, which is mounted on a metal home that is held in place with a screw(s), nut(s), Beaver State sometimes good snapped in. The motor unplugs from a small electric receptacle inside of the housing. When using the upgrade kit there is no reason out to make out anything with the wiring. The new motor will just plug into the existing electrical receptacle (Assuming that there is nothing reprehensible with the receptacle).
Ahead installing the new motor, clean the inside of the winnow housing and hold the backdraft damper to confirm that information technology moves freely. More information about this obtuse retrofit is in my resort book.
A visitor to MrElectrician.TV wrote to me and told about needing a replacement backdraft damper because peerless of the tabs had broken off. Unable to find a new one, he got the former indefinite running with a piece of dress hanger cable. No foster inside information were provided.
I commonly write the model number of the existing fan housing somewhere in the back.
In the above photo the 690NT centrifugal and winnow impeller is fully assembled happening the anticipate top ahead existence inserted into the devotee living accommodations on the ceiling.
The sunrise climbing bracket out has two tabs one one remnant that slip into the slots in the fan housing. The opposite side is held in situ with one screw next to the electrical receptacle.
With the new motor and grill installed, the old bath rooter looks like-minded a new model and sounds a lilliputian better too.

If you want a bettor quality bathroom exhaust fumes fan that is more than quieter, I suggest a full replacement with a Panasonic Bathroom Fan. I like the WhisperFit serial publication because they are compact and come with a 3″ to 4″ duct adapter as the fan is rated aside Panasonic for use with both 3″ and 4″ air ducts.
The Panasonic bathroom fans are made for retrofit also as new construction. I have done several retrofits with the Panasonic fans and they all upside-down out substantially.

You should determine ahead of time what size up duct is neighboring to the existing fan. The high-grade way is to remove the alive fan as I have seen 4″ duct connected to a 3″ canal opening night connected the grey winnow and 3″ duct connected to a fan with a 4″ duct opening.
When I do a bath fan refilling for a client I bring along duct supplies for 3″ and 4″ exhaust air duct. It's easier than having to give out and buy needed supplies in the mid of a replacement job.
