Hi, it sounds as though the blower/condenser fan motor has maybe hit something, the blades on the shaft if its not blowing any air. You can go outdoors to see if the condenser fan motor blade or cage is turning, as this is a dual shaft motor. Sometimes if the bearings wear, they will be out of balance and hit another part in the unit and bind up. I would check this for sure. If you have something slim but hard you can stick inside to see if the motor turns at all this would tell you that the motor is either bad or the blades have hit something and locked it up. Do this and get back to me. You can use my user name below. It may be a faulty blower motor. Please rate me and I know you will be kind. I will keep all of your information filed, so I will remember this unit and what happened. Please let me know.

98 volvo s70 last week I was backing up heard a boom so i stopped backed up again heard a boom again so i put the car in park then put it in drive pressed on the gas car will not go start shaking and...

I\'m thinking out loud here - if the car won\'t move when you put it in gear, it sounds like maybe the torque converter is bad. If it\'s unbalanced, you\'d get vibrations and the car may not move.

Water under the car may or may not be related. Is that maybe just a few drops, like from the A/C condensation?

If it were the water pump, then the car wouldn\'t start/run because that belt also drives the cams (without which the car won\'t run at all).

1, Check the coolant level - is it normal or low? You can dip a finger in the water on the ground and touch it to your tongue. If it tastes nasty sweet, it\'s coolant (don\'t swallow, rinse your mouth well with water and spit it out).

2, Does the car start/idle normally? If so, then it\'s something with the transmission if the car doesn\'t move back/forth. It\'s a front wheel drive car, so maybe look at the drive shafts inside of the front wheel to see if there\'s oil/grease splattered and if anything looks broken.

It sounds like the heating element is faulty. If it has a short, it will have a damaged place. A short causes a build up of amps until it can't take anymore and then a action will happen like a fuse blowing, which it the noise you hear. You can get replacement elements on Amazon fairly cheap. To fix, unplug the stove. Lift and tug on the element to pull it out of the socket. It is usually easy.

Kenmore dryer stopped running

Hi, I can determine a motor bad by the noise. Does it hum while holding the start button or is it a grinding deep sound? It can sound like the motor starts slow but once it gets going, it is ok. Sometimes the house lights will dim when the motor statrs going bad.
Let me know if I can help you further.

My Stackable washer/dryer is not operating right

Two things:

1) I would first check your water pump, if something gets in it or the water pump bearing is bad, it makes this kind of a sound.

2) If you can spin the washer drum by hand in either direction, the transmission is bad.

Good Luck!

sounds like the belt tensioner. look for any drive pulley that doesn't actually drive anything but is turned by the belt... that is spring loaded and keeps tension on the belt... if it moves freely... it needs to be replaced.

If the amp produces no boom with no signal input cables connected, I'd suggest using an LOC.

The Bose engineers in their "infinite" wisdom developed a $300 radio with no, that is NO, tone control. This means the only way to tune bass response is to reposition the Wave radio itself. If you put it in a corner of a room, it will produce the most bass. If it is only against one wall, not so much bass. To reduce bass response to a minimum, you would have to suspend the device from a wire in the middle of the room. Good luck. I would never buy a radio without a tone control; I literally inherited by Bose Wave Radio and use external speakers which do have tone controls.
