SOURCE: No Power to unit

Hi, How old is the unit? Is there a warrenty on it. If so, anything you do to it may void the warrenty. First, check to make sure breaker on the end of the plug is not tripped. It will probably have a reset button on it. If it will not reset it can be replaced with a regular 110 plug if needed. (If this is a 110 unit) If you are talking about the control panel on the AC when you say control box I think you are getting into more than you can handle and not sure that what you ordered is even what you need. If you want to get into it, first make sure it is unplugged, Take off the front cover and slide the unit from the outer cover, there may need to be a few screws removed to do this. Look at the wiring and see if there is anything burned or loose. Other than this you would have to get a meter and talk with someone on here familiar with your particular unit to troubleshoot it. I really don't think you should order any parts before you find out what the problem is. If there isn't anything that you can see that's wrong with it I would suggest taking it to Sears and letting then determine if it would be better to fix it or replace it. Hope I have helped. kstfas

SOURCE: Kenmore Elite bottom freezer refridgerator

I just went through this with my refridgerator and actually posted one of the questions. Here is what I found ........

In the freezer compartment behind the panel there is an evaporator fan which pulls cold air from the freezer and pushes it up into the refrridgerator compartment. If the fan is not working it is one of three things.. 1) there is so much frost in the fan area the fan blade is stopped and cannot push the cold air into the refridgerator compartment or the air channel is blocked. 2) there is no electricity going to the fan (usually tied to the door switch of the refirdgerator compartment, and 3) the motor is dead and will have to be replaced.

Solution to #1 - defrost but there is another problem in the "frost-free" part of the system which must be addressed or the frost will return and it will happen again in the future.

Solution #2 - check to see there is power to the fan. (most are 110VAC but some are 100VDC. Use a meter and check)

Solution #3 - If there is power, the motor is dead. Replace the motor. Be aware that AC and DC motors are different and replace per manufacture's specifications.

Code pau 41


Hello J, thank you for allowing me to assist you again!

If you are receiving an error code E41, your loading door may be ajar. Double-check to ensure that it is closed. If it is secure, reset the power to your appliance for about 30 seconds. You can do this by unplugging the unit or flipping your circuit breaker into the off position. If the error persists, it could either be the door switch assembly or your unit's main control board. In that case, a certified technician would generally replace the faulty part after proper diagnosis.

The unit turns itself on and off every 30 seconds. The screen displays hello and then 30 seconds says off and then a 30 second pause. What can I do?


This is a shut down due to an error in the system and is related to the malfunction of the main drives or the optical units.
You need to check the loading and drive sections, check the power to the main board/ processing section. Some times a fault in the mother board can result in such a shut down and will require a flow chart check up.
Take consensus without tampering.

Sears dryer model 417.84092500. It turns on for about one second, stops, then it shows error message PF. How do i fix it?


Hello & Welcome to FixYa


PF error means power failure which is generally caused when the control board inside the unit goes bad. You can try unplugging the unit for 15-30 minutes, if the issue returns then the control board needs replacement. Please get back to me if you have any other questions.

No power


Hi,
The main PSU is part of the control board. You may be lucky to find an aged fuse to replace, but it's more likely a power transistor that's fried.

Unplug and remove the control board to see which bit's toasted. Chances are it's cheaper to replace the control board - but check the probable cause - the motors are not short circuited.

When i power up my projector the screen projects some vertical colored lines and none of the buttons work. i cant even get any tpe of picture on the screen


Hello Lvhrj, Hi!, the projector unit has basically two circuit boards, one for the main board, that controls the lens, lamp, blower fans, and projector circuit controls, the second one is the power supply board, since as you mention, there is power on the projector, I suspect the problem is on the mainboard, Servicing this type of board is no nonsense, double sided and its way beyond our experience, but we do replace the entire main board, so the only solution is to replace the main board, this requires tech knowledge, if you are not that kind of person, I suggest you let the experts do it for you, call your service center, or your dealer.

Fridge and freezer stopped working.Power still on (light on in fridge). Digital control for fridge and freezer shows straight line no numbers. Any suggestions?


The double dashes in your display are for one of two reasons. First situation would be would be "you turned the unit off". Press the up arrow on the feezer or fresh food control until a 4 is in each display. Second, if the control is locked out, the board has been scrambled or failed possibly from a power surge. Unplug unit for 30 seconds, and plug it back in and try to set control's for "4". If controls are still locked out, the board (12868513) needs to be replaced.

My washer has a f1 code will not spin or wash


OK, your unit is quite unique. this unit has a integrated control design that houses the main and motor control board. both are combined on the same board. this error code represents a failed Machine and motor control board. this single control board works as the main controller and, as the motor controller as well. This board has failed in your unit and, you will need to replace this board asap if possible.

Unit will not turn on


I have two of these units (actually it is my sister and brother in law's) but they come to me to fix stuff.
Last year they came to me with this unit not working. No indication of power on the display. I diagnosed it down to the PWB Assmebly, Main. I believe they are referring to it as a Power printed circuit board (part #6871A20271A). The new board worked for about 4 months and then quit in the same manner. Also, the second unit quit in the same manner also indicating the circuit board is bad.
I don't want to throw a board at it till I know why they are burning out. Also, want to try to diagnose the board to component level ($33.28/board last year). Let me know if this helps if you have the same symptoms?
You can replace the board but my experience says it will only last for a short time till we find the real cause (Sears must know this problem exist).
