Door
 
I have an exterior door that has a stuck plunger. I have tried to spray WD-40 to free it up. It did not work. Is there something else I can use? Would graphite work?

loosen some screws( the ones holding the knobs together) and try the w-40 again.

I would remove it and clean it with some type of aerosal degreaser or electrical cleaner, then lubricate with a non oily lubricant. Often this type of problem is caused by a collection of gunk from years of well intentioned oilings collecting dirt.

So which way is correct? I imagine that WD-40 would be considered an oily lubricant. So it appears we have a disagrement. If it helps the door is only 2 years old. I would not thin that there would be a lot of build up yet.

I appreciate the advice. I just want to make sure that what I am doing is right.

troubleseekers advise is good if this needs a big fix. I see many knobs installed a little too tight that demonstrate the problem you described.

try loosening the knobs / turn the knobs quickly/ if this doesn't free up your striker take the knob apart and clean & lube as advised.

Will do. Is WD-40 an acceptible lubricant?

Big Bob 10-03-2007 10:36 AM

wd 40 has its fans and detractors.

quick easy and I know where the can is.

graphite / 3 in one oil / grease / lithium grease/ etc. will all have there fans.

Really depends on what you want to do and the result you need and expect.

Silicone spray is a good lubricant. Not oil based and once the propellant evaporates, no residue to attract dirt.

WD-40 is actually a rust remover. Works great to break rusted bolts etc. apart. While used as a lubricant by many, that is not it's main intention. You're better off with a light 3 in 1 oil or the like. The silicon spray is a good idea as well. I would take the assembly completely apart and clean it in a good de-greaser bath then re-lube it.

Also, when it's apart, check for bent pieces or fittings. Sometimes the plunger where it contacts the knob gets bent.

Ah, more descriptive. The two year old knob indeed should not have a build up of gunk that bad .Sounds like BigBob is headed with the better assumption here. If the two halves of the knob are tightened excessively, it will often bind the plunger.

You don't mention what type of lock it is or who made it. This might help.
