I think that the fan belt of the tall fan oven needs adjusting as it has started to squeak when the oven is on. It is not a constant squeal, but is an on / off squeak.
I had a book written for you and remembered something basic I learned in electronics school and had to delete it all. Sigh. So with a smile I start all over and hopefully make this short.
Are you certain there is a belt?
Let's assume there is. A belt means a motor is spinning the belt which is spinning another pulley or "wheel". You could be correct that the belt needs to be changed. They stretch over time causing slippage. That is one way you hear "squeak". The other way which I hate and am dealing with on my car right now is the pulley or pulley's themselves.
If you don't have a belt then your motor is directly running your fan. That means the "squeal" is coming from the pulley's bearings. Most fans I have seen come pre greased from the manufacturer and are not made with a hole to squirt a little inside. They are designed with an expected lifespan. That's another story though.
The bearings get too dry and they begin to, well, drag. That drag is the squeal you hear. Your warning sign that pretty soon they are going to stop dragging and just dry up and stop rolling completely. When that happens you may turn your fan on and hear a hum but the fan doesn't work. To simplify this for everyone, the ball bearings inside no longer roll so the fan no longer spins.
You may have a belt and two pulley's (or more like in a car) and have a good belt but a bad pulley. Most people throw away the product thinking it is no longer useable when all that is needed is to loosen a single screw in the middle of the pulley and replacing it with it's exact make giving the device another jillion years of use.
Now for the conclusion. If you find that the pulley is the problem, go ahead and change that belt that has never been changed to save yourself from the squeal you will hear from that new strong pulley making that loose belt squeal.
One last thing. Check by seeing if it wobbles when turned on or feels loose and slightly wobbly when turned by hand, with it turned off of course. Good luck.

If I understand this, your fan and other belts driving components in the engine bay stop squeaking when stepping on the brake? Your belts may need some adjustment to tighten. But it may be a vacuum hose leaking around the power brake chamber, or it is leaking, and sounds like the squeeking you describe. I would temporarily confirm the belt squeak by using a "Belt dressing spray" from your auto parts store, to see if it really is the belt or a possible vacuum leak. My belts squeak sometimes after the first start of the day in cold weather since the alternator is working very hard to recharge the battery after the start. It will be quieter when the engine is slowed down as in your braking scenario.
i have 96nissan pathfinder and belt squeaking when i start the engine and stop and start squeaking when iam driving and stop and come back it a new belt
You need to determine whether the squeaking is being made by the engine, the primary, the drive, or the frame. While riding, pull in the clutch, does the squeaking stop or change in any manner? Is the noise there when the engine is running but standing still? Pull the clutch lever in and release, does the squeak change or stop.
If I had to say what I think it is, I'd say it's probably the rear drive belt is not tracking correctly due to the alignment of the rear wheel. Look at the rear wheel adjusters. They should be exactly the same on either side of the swingarm. Also, the belt must be tight. If not, a loose belt will make a squeaking noise.
Hi. Usually, this will lead to the replacement of the belt, itself. Check the condition of the belt. Make sure it is not worn, or cracking. If dry rotting is visible, simply replace the belt. If the tension is beyond factory specs, adjust to correct the issue.
NOT Solution - I just bought one last week and it squeaked for me today. Sounded like a belt. As the washer added more water to the drum to soak the clothes, the squeak went away. So not sure if belt slightly out of alignment - hence it rubs or perhaps a roller knob needs adjustment is what I am thinking.
Squeaking noise often indicates problem with drive belt. If belt broke, drum will no longer rotate. Belt is similar to fan belts used in autos. Ck Sear's website for parts diagram of yr dryer. If it shows a drive belt, I would start there.
sounds like the belt is still loose and slipping,you may need to replace the belt it's possible that it has stretched and can not be properly adjusted.
the ac belt is sperate from the power steering belt.. sounds to me you need to replace the belts (both of them) but theres a idler pully in the middle of them all witch may have a bearing going out on it..i had to change mine at about 85,000.. when i had the belts off i spun the pully and it was excessivly stiff cause'n slipage and also a squel.. hope its not the alt, or water pump making the noise..they can run ya into some $$
Hi, the problem is probably caused by the crankshaft pulley! Have it replaced because it will certainly break down within a short period and can cause severe damge to your car.
