Float switch connections

I am replacing a float switch and wiring damaged by our angry Pekingese dog. (Really-- it's a long story) There are two wires connected to the switch terminals. One wire comes from the control panel. The other goes from the switch to the water valve. One of the switch terminals is marked "COM" The other terminal is marked "NC". Which wire is connected to which terminal?_

Michael Smith... Hello,

Looks like we are in luck...

My FAV website form "MANUALS"...

Happens to have your SERVICE & REPAIR manual:
Maytag JDB4000AW Service Manual

The actual description on page 29 is not all that ILLUMINATING...
... and WORSE I WAS HOPING TO SEE A circuit DRAWING to confirm what I already knew..

"Com" takes the POWERED SIDE... (hot when running)
"NC" (normally closed) goes to the WATER VALVE.

During the sequence of washing...
the controller applies power to the "COM"...

when the FLOAT SWITCH... is NOT floating power
continues to be "ON" to the WATER-VALVE...

When the water get to the operational (float)
level the "NC" (normally closed).. OPENS and shuts
OFF the WATER VALVE.

I ONLY looked halfway through the "service" manual...
before I came to the conclusion there were NO SUCH
circuit or schematic drawings... (verified on 2nd pass).

Even after to careers in electronics... I hate working on
ELECTRIC stuff... My personal pleasure would be to invite you to look at the No Contact Volt Tests... (NCVT)
Amazon com no contact volt test

For between $10 & $20 you can be the proud owner of a
NCVT... Mine is a KLEIN... (long ago.. & far away).

Turns red & chirps... when it gets near power
(so I won't have to (turn RED or chirp)).

Klein Tools NCVT 1 Non Contact Voltage Tester Electrical Tools Amazon com

Still got it... Still love it...!!

Hope this helps...

and I am glad to hear it is a long story rather than a
tragic one...!!

Give your darling Pekingese message for me...

2004 Big Dog Chopper cuts out while riding


Hi, Anonymous and the usual suspects are:
1. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
2. Failed alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. Failed main circuit breaker or ignition switch, check for loose connections and continuity.
5. Failed system and or ignition relay, check for continuity.
6. Failed ignition coil, stator, magneto, ignition/electronic module.
7. Failed CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.
9. Faulty neutral, side stand or clutch lever safety switch.
10. Faulty or corroded kill switch.
11. Accelerator pump damaged or not working.
12. Water or dirt in the fuel system, carburetor or filter.
13. Restricted, blocked or kinked fuel line.
14. Fuel tank empty.
15. The gas cap is not venting properly or fuel tank venting system blocked, loosen gas cap and go for a test ride.
16. A failed fuel pump, pressure regulator and or fuel injectors.
17. Vacuum line from intake manifold to petcock broken, cracked, or not attached, carburetor vent line plugged.
18. Needle and seat stuck closed in the float bowl.
19. Petcock clogged or damaged.
20. Lean angle switch is faulty or needs adjustment.
21. Catastrophic engine failure, perform a compression test.

How to fix blown sub (replace fuses etc)...? stop protective light illuminitating?


The first thing to try is to disconnect the sub and all speakers from the amp's output block. The only things that you need connected to the amp are the 12V power, the ground wire, and the remote wire to turn it on. If the protection light comes on with only these three wires connected - your amp has been damaged internally and will either need to be repaired or replaced.

I put the feed dogs down and now they won't go back up, what do I do now?


The feed dogs are driven by the feed driver mechanism, turn the hand-wheel forward and the feed dogs will come up. (Providing you have the feed dog switch to the up position).

KENMORE DEHUMDIFIER MODEL 580.51300100 DOES NOT RUN, NO POWER LIGHT AND NO FAN RUNNING ETC


First, check the source of the power to the unit, Has a circuit breaker in your home's circuit breaker panel been tripped? If so, unplug the unit, before resetting the circuit breaker. If that's not the case, check the outlet it's plugged into. It may be damaged or have a loose wiring connection. Be sure to turn the circuit breaker for that receptacle OFF, before removing the cover plate.

If all of the above checks out OK, check the water collection bucket, as it may need to be emptied and/or the bucket was not reinstalled properly or the float valve in the top of the bucket is stuck in the UP position, If so, jiggle the arm of the float valve to get to return to the DOWN position.

When reinstalling the bucket, be sure that it fits "squarely" into it's holder and makes firm contact with the bucket safety removal switch.

I hope this helps you to troubleshoot & solve the problem. Thanks for choosing FixYa.

The dishwasher is stuck on drain, I think it has something to do with the overflow. Can you help? Thanks. I have checked all out lets & water in & filters.


Hi

The issue seems to be with the float switch assembly that is bad and should be replaced. Float assembly is found inside the dishwasher's tub, on the bottom. The water that fills the dishwasher lifts the float, and when it reaches a certain level, it acts as a trigger for the float switch. The float triggers the float switch to shut off, thereby shutting off the flow of water into the dishwasher. A defective switch may interfere with dishwasher's filling and/or draining ability. Use voltmeter to test the switch. Set the device to the ohms setting x 1. Take each probe and touch them to one switch terminal each. This should produce a reading of either zero or infinity. Continue to touch the probes to the terminals, and press down on the switch's button. The reading should change to the opposite extreme. If the switch fails either of these tests, you should replace it. Hope this helps...please post back for further assistance.

The dishwasher won't pump water in. how do we fix it?


Hello there and thank you for choosing fixya:
If there's no water entering your dishwasher, check these:
Water-inlet valve The water-inlet valve lets water enter the machine. If this valve is defective, you need to completely replace it. It's usually located behind the lower access panel on the left or right side. It's the device with the main water line (usually copper) from the house, a rubber tube to the dishwasher, and two wires attached to it. Float switch The float switch is a small electrical switch that's located right below the dishwasher "floor." Above the switch, on the inside of the dishwasher, is a plastic cylinder that floats up as water fills the dishwasher. If this switch is defective, or if the plastic float gets caught or trapped in the raised position, the water can't enter the dishwasher. If the float switch is defective, you need to replace it. To determine if the float switch has failed

My gas guage stays on empty and the tank is full


Sounds like your senor in the gas tank it self is bad. Most cars have a float that read out how full the tank is and when it goes out it will stay stuck showing you on the dash that your tank is empty even though it is full.
