Heater controll switch


Hello, I want to tell you about some of the knobs for the temperature control switch, if that is the switch you are referring to.

The way some of the knobs are made, they have a 1/2 moon shape with a metal clip inside them on the backside of the knob. The 1/2 moon shape is also present on the control shaft the knob fits onto. When the knob breaks and splits, the knob rotates around the temperature control shaft without moving anything. From the driver's view, the knob is normal.

You would need to pry off the knob and inspect it, then rotate the temperature control shaft with your fingers or lightly grab it with pliers.

I have a 1998 ford taurus and the mode selector control knob spins and all i get is defrost. any ideas how i can get the knob to work?


the knob may be broken or worn were it attaches to the switch.if you remove the knob and use a pair of pliers to turn the shaft to see if the modes change,if they do then you need to replace the knob and make sure the metal lock tang is with the new knob that securely holds the new one on the shaft.if not then the switch is bad.the rear of the knob should have a odd shape that fits the same shape of the shaft it attaches to.

My gaggia classic steam control knob is inaccurate and fails to turn off the steam completely. the system leaks a lot of water into the tray


you should take out the knob first, than you try to disasembke the SHAFT of valve from the valve body, in this types(small espresso coffe machines) usualy producer use conical valve, without seals she close metal to metal, when you get out the SHAFT you will see one line on the conical end. for repairing it will be enough to visit one metal vorkery where they will take a small amount of brass from end and polish it. then you put it back and work again with your machine. During assembling valve change 2 o rings and put one fitting 1/4'' to block the shaft coming out.

ps: notice you only polish the SHAFT , dont let them to short the more than 0.5 mm

2oo2 ford expedition heater will not get warm,thermostat and coolant replaced.The temperture control knob turn to cold goes cold,but when turned to hot ,only gets a little warmer.The blower is working...


Before you look at blender doors and Electronic stuff check out your Heat knob. You did not say whether you have a digital or manually controlled heater. On the manual controls the heater knob is subject to breakage.

If you take off the knob and look behind it, there is a metal clip with an irregular shape that fits onto the control shaft. The knob housing is subject to cracking. You can take a pair of pliers and gently turn the shaft. Your heat should immediately increase provided the vehicle is hot and the heater controls are set.

A new knob runs about $9 at a Dealer. Salvage yards want to sell you the entire control assembly and not the knob. If you think about gluing it, you will need to know where because the outer ring limits the turning range.

If you have a Digital dash, there is a set of diagnostic functions that will identify the defects. The problem is having references to the Codes, the technical terms, and knowing how to initiate the test cycle. You can try a Browser search for "Ford Climate Control", add Diagnostics, add problem solving, and you may find those answers.

I hope you are happy with my Solution and that you get your ride working.

Cannot get the windshield wiper and light knobs off in order to remove the cover. They do not just pull off?


For everyone's future reference, the windshield wiper knob has a spring metal clip holding the knob to the shaft.
There is a small slot under the knob. Starting at the back edge of the knob, use a small screwdriver to push into that slot in the same direction you want to remove the knob.
That will push the metal clip and release the knob.

Knobs wrinkle on my LG LGR30855ST range.


The plastic shaft on the knobs split and loosen. I have the solution for that, but I need one metal insert that goes over the gas valve shaft and into the knob. For those that have the split knobs. This a bit of work but it works great. Remove the two screws from the back of each knob. Go to a hardware store and find the thin brass tubing that most have. Pick the tube that just about fits over the plastic shaft. It will fit over the tip but will not slide down the shaft all the way. Now pick a brass washer that the tube almost fits into. (You have to do a bit of tooling on both the washer and the plastic shafts. What you will end up with is a brass tube soldered to the washer that fits over the plastic shaft and is screwed to the metal insert in the knob from the inside. First take the tube and file across the top of the tube to make teeth. Now slide the cutter tube down each shaft while rotating it. This cuts the shaft to exactley fit the tube. Drill the washer to also exactly fit tube and cut or file the washer to fit into the knob at the bottom of the shaft. Cut the tubes to length, press fit them into each washer (this should be very tight and solder each washer to the tubes. Place the soldered unit on to the plastic shaft of the knob. Drill two number 4/40 size screw holes into the washer. One on each side of the shaft. Just start the drill into the metal insert. Do not drill through now. Remove the metal insert. (take a small screw driver and put it into the space on either side of the metal part of the knob. Not between the metal and the plastic knob though. that may break the plastic. The metal insert comes out fairly easy. Once it is out finish drilling the holes with a 4/40 tap drill. Tap the drilled hole with a 4/40 tap to make threads. Screw the tube and washer assembly to the metal insert. The screws should be flush with the back of the metal insert. Place the metal insert back in the knob. You now have a sleeved knob that will never break again. This is how it should have been made in the first place. I did this in a few hours on a Sunday afternoon. The parts including the 4/40 drill and tape were about $13. It is not as hard as it reads. LG has a quality issue, but does not want to step up to it.

Kenmore 90 series washing machine


there is a coupling between the gearbox and the motor, it is broken, it is easy to replace, and inexpensive
the coupler can be purchased at a local parts store
'Kenmore motor/gearbox coupler' will get it for you, there is only on for all the models.
it is an easy fix
  • unplug washer
  • remove trim ends of control panel
  • remove phillips head screws from bottoms of control panel under where trim was
  • slide control panel forweard & up about 1 inch, then flip over the back of the control panel, do not dislodge the air hose
  • remove brass clips in rear corners of top with screwdriver, remember how they fit
  • unplug lid switch connector
  • lift body 1inch and slide forward to remove
  1. front center is the motor pump and gearbox
  2. do NOT disconnect hoses
  • remove spring clips holding pump on to motor shaft, note where they go for reinstall. there may be a lock screw in the top right clip.
  • swing pump to the left and use a string or bread bag tie to hold it out of the way.
  • remove spring clips holding motor to gearbox shaft, note where they go for reinstall. there may be a lock screw in the top right clip.
  • heave motor forward, to separate the coupling
  • remove coupling halves from gearbox shaft and motor shaft and discard.
  • using a wooden dowel and hammer, on the center of the new coupling halves, drive them onto the motor and gearbox shafts, (dont hit the fingers, they break, note the new couplings have metal centres to solve ongoing problems.)
  • rotate gearbox coupling, 1 up 2 down
  • rotate motor coupling, 2 up 1 down
  • install rubber shock pad on gearbox coupling
  • install motor on shock pad
  • reinstall spring clips and lock screw if fitted (bottom first, rock the motor on rubber shock mount to ease spring clip installation)
  • rotate motor shaft to align with pump input
  • install pump on motor shaft
  • install spring clips and lock screw if fitted
reinstall body in reverse order

it takes less time to do the repair than it takes to type this

Volume Control


The volume control shaft lube, over time and heat exposure, will flow down and corrupt the contact between the volume twister and the spring loaded sensor. Pull the cover off the tuner, locate the volume control and take out the two screws holding it in. It looks like a small circuit board with the volume twister attached.
The base of the twister is hooked to the circuit panel by four metal tabs. Pry these guys gently away and pull the twister free. There will be a metal disk at the end of the volume control shaft, and will have a goopy lube residue on the face of it that can be cleaned with electric contact cleaner or some other kind of solvent. Wipe it clean,(do not immerse) reattach, and test. Worked perfect for me.
Good Luck,
F

Turning off oven


what brand is it and what is the model no.
some knobs have little metal clips inserted in them to help grip the shaft. when buying new knobs they dont always come with the clips inserted in them, you have to remove them from the old knobs.
hope this helps
