Will not turn on. Checked breaker and plug, microwave is getting power.


Rick,
Good possibility that you have a blown fuse. Follow the directions provided below to find the fuse.

Unplug your microwave and turn it around and remove the screws holding cover on and then remove the cover. Be very careful about touching electrical connections because there can still be some live current stored in the capacitor. Look for where the power cord goes into the back of the unit and follow the black wire from the cord to where it ends. It should stop an either a circuit board or a fuse holder. Make sure that you replace the fuse with the same amperage fuse as what you take out. You will find the amp rating stamped on one of the silver collars on each end of the fuse. Good luck!

Nail gun will not fire green light on gas ok after drop on congrete floor


A quick diagnostic check. First remove gas cell press nose against solid surface to dispose of any gas that may be in chamber.
1. Insert battery - LED should flash.
2. Press nose against solid surface - LED should be lit permanently (if still flashing possible fault moulded circuit board or fan motor micro switch lever, if flashing red green high possibility motor fault). Listen to hear fan running if not heard fan blade may have fallen off motor.
3. While still pressed against solid surface press trigger and watch LED - LED should blink off then light again (may flash red on guns newer than 2006) If does not blink fault either Spark unit (controller) or moulded circuit board trigger micro switch. To test for LED blink again release pressure on nose then press again. The blink indicates that a spark has been sent to the spark plug.
4. If 1 to 3 are OK problem most likely gas related or leak in seals. Ensure driver blade not still forward a possible fault of sticking forward after being dropped is nose slightly bent this traps the driver blade when first fired and does not return. (jammed nail gives a similar fault.) If nose is the fault it will require a new sleeve.
The moulded circuit board is normally cheapest then spark unit and sleeve roughly about same price the motor is most expensive.

Hope this has been some help to you.

The board should be replaced before the unit will operate properly. Be sure to check out all circuits to make sure there is not some kind of short. If there is, it may burn out the new board also.

Washer had just started and i started to smell something, and all of a sudden a noise came from the washer and then smoke came from machine really bad, the noise sounded like air escaping


Looks like something is short circuited & due to which there is burning smell coming out of the machine. Disconnect the machine immediately & inspect the insides of the machine. Locate the burnt motor or burnt wires. You heard the noise coming out of the motor. It could be dislocated brushes due to which the motor could not rotate & in turn it burnt your motor.

While driving heard a bang smoke from exhaust and water pouring out exhaust think it might have something tto do with radiater


G'day.
Unfortunatly sounds more like a blown head gasket.
Remove the spark plugs & kick/crank bike over & see if any water comes out of the spark plug holes.
If it does then the head gasket is blown.

Hope this helps.

I recently revisited my car after a few weeks out of my hands, and seconds after turning the key and the unit powering up, the sound of popping and shrapnel in the amp was heard and the smell of smoke...


What has probably happened is a short somewhere in the amplifier. Here are some possible scenarios:

1. When the new capacitors were installed, make sure that no solder shorted any pads on the circuit board to anywhere else.

2. There is probably a resistor upstream of the capacitors that has shorted but still appears to be fine. Look at the circuit board & follow the traces that connect to the 2 terminals of each capacitor and follow them to other components. Examine them very carefully. Pull on the wire terminals of upstream & downstream components to ensure they are solid. Check each side of the component with an ohm meter. If a zero resistance is given, or no (open) resistance is given the component could be in question. To properly check it out, one side of the resistor must be pulled up from the board, then check the resistance again. If out of spec, it would need replaced & then it would properly voltage limit the capacitors, keeping them from going up in smoke.

3. This can be a very tricky problem without a schematic. See if you can get your hands on one, it makes circuit tracing much much easier

How do I fix my Endurance Treadmill TF3i Err7 problem? I stopped during operation.


Unplug unit remove motor shroud check connections on lower board (incline board). I believe their is a 3 amp fuse in circuit check with multi meter to see if open replace fuse power up unit and if it blows the fuse then replace incline motor and if not, then use engine mode press stop then Incline + or - to force incline up to max incline then bring it down to 0 then turn off power then wait 10 seconds then hit power on then if error does not appear then hit start and resume using unit. If the procedure above does not activate unit then replace board.

I have replaced wiper motor 4 times last three years, wipers come on by them self run minute or 2 shut off, and it seems to start after I use touchless car wash. After I replace motor wipers work fine for...


This is really an easy fix. The wiper motor assembly is on the firewall, just right of center. The wiring can be unplugged before the circuit board is removed, or afterward. I found it easier to unplug it after the circuit board was removed. There is a flat cover that is held on with three torx screws (T20). Remove those screws and remove the cover.
The circuit board will now be visible. Remove the circuit board by grasping the wiring connecter and gently pulling it towards the front of the vehicle. When the circuit board has fallen free, unplug it from the wiring harness if you haven't already done so.
The solder joints that connect the wiring socket to the board go bad on the board.  Just resoldered those and re-installed the circuit board. 

Good luck and hope this helps. keep me posted, be glad to help.

Hello,
The problem with the TOC reading and then appearing C13 is a problem with bad electrical contacts.
Remove the connection to the mains outlet, remove the top cover (5screws) and the remove the 2 paper flatcables that connect the main PCB and the disk unit on both sides. Plug them back in and possible your problem is solved.
A better solution is, of coarse, to replace both cables by new ones, as the quality is rather bad, and once disconnected, they should be replaced.
Good luck!!!
