Faulty switch on FT 411e

The handy has a faulty on/off switch which works sometimes when I apply a bit of lateral pressure on it.
I would like to replace the switch and would appreciate a part No and place where they might have one.

How accessable is this switch ?? Could you use a pair of pliers to tighten any tabs on the switch itself? Could you put a dab of LIGHT machine oil into it?
Hope this helps

Drill runs until pressure is applied to the bit. then the motor cotinues to run but the chuck stops spinning.

It sounds like the gears themself are stripped. On the inside of the drill right behind the head is a gear that turns the head itself. When that gear is stripped the head will spin sometimes withou pressure but when pressure is applied the head will not spin

I have a Goodman GMP125-5 furnace. A year ago, my circuit board was replaced by a repairman. He also replaced the heat exchanger, because he said it was cracked. It worked great until about a month ago....

it would sound like the pressure switch is not working you can take off ther tubes and by hand put a small drill bit in the and clean the switch , some times this works , on some you can jump out the switch and try and fool it in too working

My freezer seems to be running all the time.

This is normally due to faulty thermostat,if it has a temperature knob to raise or decrease temp try turning down until stop then apply a bit more pressure and you should switch it off .If not try turning other direction ,the tight spot at the end should switch it off .
If not replace thermostat
hope this helped

Our washer overflowed last night. no warranty on

Overflow is usually caused by a “stuck-open” fill valve, and the cold water half of the valve is usually the culprit. This can also be caused by the fill system control components: pressure switch, pressure tube, or pressure tube dome/port.First of all, determine whether your overflow condition is mechanical or electrical. Start the washer filling, then turn the timer off by pushing the knob in. If the fill continues, pull the washer plug. If filling continues with the washer unplugged, you have a mechanical problem - nearly always a stuck valve ***’y. Replace the fill valve.i f however, the fill stops when you unplug the machine, you are looking at an electrical fill control problem, Here a small piece of rubber or plastic tubing is handy. Unplug the washer and open the console where you’ll see the pressure switch. This is the switch with a small rubber tube, usually clear, sometimes black, attached. Pull this tube off and replace it with your short tubing. Blow a bit of pressure into the switch using your mouth, and listen for a click, then another when you release the pressure. Hear two clicks? Good! The switch is probably OK, Plug the washer back in (being aware that components in the console are now ‘hot’ and start the washer filling again. With it filling, again blow a bit of pressure into the switch. If the switch is good, the fill should stop and the machine should start to agitate.
This verifies that the pressure switch is working, and causes us to suspect the pressure tubing or a clogged port/dome to which it connects. Wipe off the end of the original tube you removed from the switch, and blow into it. You’re blowing air down into the tank now, and you should feel very little restriction. If it is very hard or impossible to blow through this tube, the tank dome or port is clogged..
Whatever your brand, if air can’t be blown back through this tube, the port or dome will need cleaning.
If you have no trouble blowing pressure through it remove the tube completely and inspect it carefully. This tube must not have the smallest hole in it, and we sometimes see them worn through or, more often, chewed through by mice. while it is the least common cause of overflow, it does happen and is easily overlooked. sometimes this tube will swell and loosen a bit, leaking air where it attaches to the tank fitting. If you suspect this, or the tube fits very loosely, simply cut 3/4” or so off the end and push it back on.

I have a goodman gcs90703bxa flashes 3 times blowed in the pressure hoses went from 3-2 flashes what could be wrong?>

flash 3 is a blocked pressure hose. the switch is open. flash 2 is the pressure switch stucked closed. if you applied pressure to the swich you may have damaged it . It typically clogs on the Induced draft motor housing on the bard fitting that the hose from the pressure switch connects to. sometimes if you take a paper clip and **** it out. but never apply pressure or tools to the switch.

Powerbook g3 will power up for 4 sec. then shut off

Hi Alienlogic,

Several points here:
1) More info as to make/model, and type of powercord would have been helpful.

2) From your description above, it sounds like you have a faulty connection in the laptop's DC/Sound card (the small circuit board that the power cord plugs in to). You can sometimes get a temporary workaround by rigging a way to apply gentle pressure on the plug to keep it connected, say with a rubber band or the like, but the only real fix is to have the board fixed or replaced. Sooner or later, the workaround - won't any more.

3) With most iBooks and Powerbooks I've worked on, this involves nearly complete dis-assembly of the computer, and you have to find a working part, or be handy enough with a soldering gun and lucky enough to have a break that you can fix yourself.

4) Parts are for-sale on eBay, or from other parts resellers on the web.

If I can be of further assistance, let me know. If this helps or solves the issue, please rate it accordingly.

Thanks in-advance,
