Hi sorry about the bad video! I have a work pool quiet partner 2 that turns on but won't run threw a cycle ? All that turns on is the lights normal and heat dry can some one help ?


see this causes and fix it. God bless you
Power Supply

The main power supply is the first thing to check. Also remove the toe kick and the cover on the power box and check the connections. Also check for 120 at the power box

Hi - Limit Fuse

This will fail if your dishwasher overheats and occassionally with power surges. This is easy to check, inexpensive and a quick fix. Just check the terminals for continuity ( remember always remove one wire) if you have none replace the hi limit fuse

Door Switch

This is the second place to look. Again an inexpensive easy fix. The following video will walk you thru chechking the door switch The power comes into the main power box and usually runs to the door switch next before entering the main control module.

Main Control Module / Timer

The main control module or mechanical timer controls all the functions of the dishwasher. To check this you will need to find the 2 leads that supply the power to the control. They will be marked on the wiring diagram. They usually come from the hi - limit fuse or the door switch. When the door is latched you should have 120 volts entering the main control. If you do not the problem is not the control. If you do have power entering the control but none of the functions work properly or it does not respond at all you will need to replace the control module. , this is easy to replace but not very inexpensive to purchase. Consider the age and overall condition when purchasing this part.

Motor

The motor may have failed. If the control illuminates on electronic versions the problem may be the motor. To check the motor refer to the tech sheet located behind the console cover on most models, this will sometimes have the ohm reading of the motor. Also check each lead to the metal housing of the motor to check for shorts in the motor. If you do not have the ohm reading specicifications, check for continuity if none replace the motor . Make sure the motor is receiving power

Float Switch

If the float switch has failed or is stuck the dishwasher control may not respond. The float switch is easy to check and replace.

We a Kenmore Elite clothes dryer (Model # 110 70972990). Monday there was a power outage that happened while the dryer was running. Hours later when the power was back on, we tried to finish drying, but...


There is a thermal fuse. If your lint filter is on top of the machine it is in the rear of the machine behind the removable panal near the exhaust port. If the filter is in the door the fuse is behind the kick plate on the top of the blower housing they are usually white plastic. But a power outage won't blow the fuse

This solution is for a Polaroid flm-373B 37 inch LCD TV. I noticed your TV is the flm-3734B. Hopefully this solution will work for you too.

I suspect you may have 2 capacitors in your control module that need to be replaced. When these caps start to go bad it will often show up as a problem with the sound. However, when they get really bad they can prevent the TV from turning on. Please see the link below, posted by stiv0. It gives detailed instructions on how to replace these caps and to tell if they're getting bad. If you follow these instructions you can take the back off the TV and check out the caps. If the tops of the caps are bulging they need to be replaced. Just be sure to replace them with the correct value (1000uf) and use caps that are rated at a higher voltage than the originals. I replace the 10v caps in my flm 373B with 25V caps just to be on the safe side. If you know how to solder this is an easy and inexpensive fix. If you don't know how to solder find a friend who does. These caps have positive and negative terminals. It's important you solder the new caps in with the correct polarity. Stiv0 gives instructions on this. Even if the caps aren't bulging this fix is so inexpensive, less than 10$, that you may want to try it anyway. I hope this helps you out.

When I turn on the TV it has a loud squeal for about 10 minutes until it seems to warm up.

TV won't turn on


Hello Marie,
I am sorry to hear about your situation. Most tv's do have an internal fuse, so if you open the chassis (which is the back part of the tv and slide it out and away from your circuit boards) the fuse will be located where the cord comes into the circuit board. Look for burnt or scorched spots on your circuit board also while you have the back off. I am sorry to say that most often than not in cases of lightning strikes the damage is expensive to repair and replacement of the devices is usually cheaper. Since the strike got a lot of your devices, it is not looking good. If you have further questions or need more assistance please let me know and I will be more than happy to help.

If you do not mind please rate my help, I would appreciate it. Thanks

TV turns off/on by itself


thats why you got this TV for free I'm afraid. Your problem will cost more then the set is worth to have it repaired. Unless you understand how the differant circuits work, and know how to read a schematic, follow the circuit flow, and use a multimeter, this will not be an easy fix for you to do. There are components in the power supply that need to be replaced. Good Luck
