Question about Broan-NuTone N-8663RP Combination Light Fan Exhaust Fan

1 Answer

To replace a bulb I pulled down on the diffuser, expecting the tension wires to be holding it up. After forcing it down, it broke off and there are no wires. I have three more bathrooms with the same problem (burnt bulbs) in a two family I just bought. Obviously the previous owner couldn't figure it out either. I'm ready to rip the whole unit out and replace it with a "standard" one. What am I missing?

I have the same fan and it is a pain to replace bulbs. There are two "V" shaped springs that hold the diffuser in place on mine. I pull the diffuser down until the springs (actually heavy gauge rods) are fully extended, maybe 4-6 inches. I then tip the diffuser and get my hand in to remove and then replace the bulbs. If your units were "altered" by someone forcing them in the past, you may have bigger problems. The springs are hard to bend to get the diffuser down and the upper part of the springs actually rub on the metal housing of the fan. Perhaps a little WD40 where the springs enter the metal housing will help a bit.

Hood release handle broke off

On some vehicles the hood latch can be released by working from underneath and using a coat hanger with a hook as a tool. It may be necessary to have someone push down on the hood while the coat hanger is being applied to relieve spring tension

The light diffuser cover is broken. The model number of the range hood is HO60488. The range hood dates back to possibly the late 1950's when the house was built.

When faced with the total unavailability of replacement parts, its time to get creative, and make your own diffuser cover. Flat ones
can be easily made - find anything plastic that's semi-translucent (like a plastic milk bottle), and cut it with a utility knife.
I have also used a utility knife to cut a polystyrene diffuser cover
originally intended for a 2-ft x 4-ft suspended ceiling fluorescent light fixture.
In case the diffuser cover you make wants to burn when placed close to a light bulb, replace the bulb with a CFL (compact fluorescent) bulb, which run MUCH cooler than incandescent light bulbs.
Old lampshades can be cut and used, but may need to be ironed flat. The major advantage of lampshade material is that
it can be folded over at the edge once or twice, which will fill space - and possibly hold the cover where a plastic sheet might be too loose.
You'll know that your efforts have met with success when you can easily remove your ne diffuser cover to replace the light bulb.

The fridge side by side is not working. but freezer is working. Help

Dear espa8,

I'm sorry to hear that the lights in your Sub-zero unit are not working. It is unlikely that all the bulbs went out at the same time. You most likely have a bad light switch. If you open the refrigerator door & look upwards you will see two white switches. The switch on the left controls the lights. The part number to this light switch is 7014646. We can supply you with light switch replacement instructions if you contact us directly. Make sure that you turn the unit off at the circuit breaker before changing the light switch.

If you do need to replace bad bulbs, you will want to first remove the light diffuser. This is the plastic cover that the lights shine through. To remove the diffuser, first pull the clips located on either side of the rear of the diffuser to a down position. This should free up the back of the diffuser, allowing it to swing down and be removed. The bulbs are a narrow 40W appliance bulb found at most home improvement stores.

How do you change headlight bulb in a 1998 suzuki x90?

Behind the headlight assembly is a large weather boot. Grasp the small portion that the wires come into and pull it straight out to remove the wiring harness. Grasp the large weather boot from the bottom and pull it up. Work your way around the rim and remove it. Yank it off the headlight bulb.

You should then see the headlight bulb and a large wire holding it in place. At the bottom of the assembly is a clasp that holds the wire in place. Work the wire out of the clasp and pull it all the way up.
The headlight should now be free and able to be removed. Remove it and replace it with a new one. Align the three tabs of the bulb accordingly; you'll see two of the slots for these tabs at the bottom, the third is at the top. Make sure that the bulb is inserted completely underneath the wire hold-down. This hold-down is required to keep the bulb from moving around. Ensure that you do not touch the bulb with your bare fingers.

With the bulb inserted, push the wire hold-down down into place and lock it into the clasp. Push the large weather boot back on, taking note of the "TOP" label. Push the center portion of this boot around the back of the headlight bulb.
Reinstall the wiring harness and test the light.

How do I install a low beam bulb on a 2005 volvo s40

1.If you did not put spare bulb in glove compartment for emergancies (for shame!), buy H7 bulb (W-Mart is best bet). Should be about $8.00 each. The two pack is a better buy.
2. Open car hood. Behind the bulb is a black plastic "peanut butter lid" type of cap that seals the bulb in the housing. Unscrew this cap (1/16 turn) and PUT IT SOMEWHERE SAFE.
3. You will now see back of bulb. Pull off the power wire.
4. At top of bulb is a tension wire holding bulb in place. Unhhook the wire and it will hinge down out of the way.
5. Remove bulb (note its orientation) and discard.
6. Take new bulb out of package, but DO NOT TOUCH GLASS. Only hold bottom. Finger oils on glass will cook and reduce bulb life. Wipe glass clean just to be sure.
7. Install new bulb using same orientation as old bulb (it will not fit any other way) and re-latch the tension wire. Re-attach power wire (a dab of dielectric grease here would make for a professional job).
Get black cap from your safe place, note which part is bottom, and screw back on (1/16 turn).
8. Test the light, close the hood.
9. Put spare bulb in glove compartment so that next time bulb dies

Grey cloud

This sounds like a diffuser problem. Basically the LCD Panel is defective.

32" LCD TV use about 8 horizontally mounted flourescent bulbs. They use a plastic material that diffuses (spreads) the light from each bulb evenly on the screen. If this Diffusion Material becomes wrinkled it will leave a grey cloudy look on the screen.

It is possible that the LCD Panel Glass is defective buy honestly I would guess the diffuser.

This isn't cheaply repairable and it is better to replace the TV unless you are experinced with Electronics repair. There may be a possibility to pull this material out and replace it with something readily available from Home Depot but I have not tried this before. It is possible to pull this from another LCD TV.

Changing motor hayward 1.5 HP

Super pumps are very easy. If it is a northstar it is more difficult. Super pump. You will need 1 motor, 1 pump seal, 1 diffuser gasket, 1 housing gasket. turn off breaker, disconnect wires -noting whether it is 110 or 220 volts- , unscrew four bolts on back of pump housing (shaft side of motor), pull out motor with rear housing and diffuser (sometimes diffuser sticks inside), on wire side of motor hold shaft with wrench (flathead in some cases, but it is harder), unscrew impeller counter clockwise (like normal screw - you will nee a big pair of channel locks or a strap wrench), there are two pieces of the back housing and once the impailer is off you can remove the half that is closest to the end of the shaft to reveal four more screws, unscrew those four screws. screw back part of rear housing onto new motor. Install new pump seal to front part of rear housing and impeller, slide on front part of rear housing and then screw on impeller while holding shaft on wire side with wrench (only hand tight), replace housing gasket, replace diffuser gasket, slide into front housing and screw in four bolts. If electrical was 110 you will need to move the jumper on the wire end..if it was 220 then just hook kup wires...doesnt matter which is which as long as green or bare goes to the ground screw.

1994 Toyota Camry Tailight Out

They are indeed accessible from the back of the trunk. In your model year there are two or three plastic pins holding the carpet to the metal so you will not see the bulb and wires. Pull the pins out with pliers (might use a bit of force) and you shall uncover the secrete wires leading to the bulbs. Screw the bad one out and you can get a replacement from a parts store.

2003 trailblzer head light bulb replacement

on a 2003 Chevy Trailblazer, you have to remove the grill to access the back of the head lights. It takes a good pull (don't be afraid to use a little force). Pop the hood and there 4 metal pieces that slide up and several plastic pieces that pop up. You will see the lips on the metal slides (about an inch in width) and you pull those up to loosen the grill. There are 2 of these slides (one on each far side, almost hidden) that are hard to get your hand into that you might need a screwdriver or something for leverage to slide them up. Then pop up the plastic pieces holding the headlamps in place and with a little force pull the grill off.
Then you can access the back side of the headlamps to replace the bulbs.

Replacing the headlight bulbs on 2005 Ranger

Having just purchased a 2002 Ford Focus I found that the passenger side headlight had gone. Stumbled accross this thread and thought "looks like a pain".
Popped to Halfords and picked up a H1 bulb, went home and had a look under the bonnet.
Armed with just a screwdriver I managed to change the bulb within 10 mins. Flicked the headlight cover off using the screwdriver for a bit of leverage. Unpluged the headlight and flicked off the retaining clip. Removed the bulb.
Fitting was even easier - Put bulb in place, clip the retaining clip in place, plug in and replace cover.
Job done within 10 minutes with no prior experience of Fords.
Hope it helps
IMPORTANT!!! The retaining clip does NOT just flick off. Tried that and broke the plastic stop that holds the retainer clip and allows it to apply tension to the bulb! The retainer wire is held in place on the bottom by a screw and clip on the bottom and is locked into a plastic clip on top. To remove the wire, push the wire down and towards the passenger side of the car, it will dislodge and you can then lower it to remove the bulb. Once the bulb has been changed, you want to replace the wire the same way to protect the plastic clip. I don't know what I will do about the plastic clip now, the retaining wire has no tension and I'm afraid the bulb will not remain seated properly. However, knowing what I know now, I agree with the above answer: Done in 10 minutes without prior experience with Fords.
=== Just finished doing this. A small mirror and a flashlight make this job simple. It's very easy to do once you can see the top of the clip.
small mirror and flashlight are essential, look at the way the retaining wire seats before you unclip it. flat side of the bulb houseing sits at the bottom of the access hole. retaining wire clips bottom to top. I had a hard time with seating the new bulb and had to figure out the retaining wire clipped from bottom to top because I didn't look at it before I unclipped it. obviously fords designed this for ease of manufacter with very little regard to the average layman who would do the replacing.
