How to fix a striped door hinge screw

Hinge is loose on door so you go to tighten the screw and oops it won't tighten. Not a good idea to put a fatter screw in its place cause the screw head won't sit right and will cause other problems putting the same size screw but longer might work but not always possible. Here is the fix.

  1. Support door as to not to stress other hinge.
  2. Remove screws from hinge plate
  3. Apply wood glue to holes, Insert wood splinters, tooth picks, wooden match sticks into screw holes until tight.
  4. Allow wood glue to dry, trim flush.
  5. Re-install wood screws, until snug, don't over tighten.
Now good as new. I hope this trick of the trade saves you money and time.

wiring schematic for a upper thermostat

Jan 2013
1) Copy following links for wiring upper thermostat:

2) Thermostat must sit flat against tank wall to read correct temperature, and entire opening must be covered with insulation so cool room temperature will not interfere with temperature reading.
Be sure to put cover back on side of tank for electrical safety, and to prevent any possible fire caused by melted parts and overheating.

3) Tighten wires very tight under screw plate, and make sure only copper wire is used, and all wires under plate are same gauge, do not mix stranded wire and solid wire or stranded will become loose.
Only copper under the screw plate and cut back insulation so no insulation gets under screw plate.

4) Add comment and say what you are doing

enough hot water for 1 bath. Replaced upper and lower elements and replaced both thermostats. could it be a sedament problem? heater is 5 years old. I never ran out of hot water before now.

You have 240Volt Marathon water heater.
These heaters have element burn-out problems.

Yes sediment can cause decreased amount of hot water when water cannot circulate around lower element, and sediment can cause lower element to burn out.

Following list is overview of tank troubleshoot:

If you have some hot water, then that says several things:
-Upper element is working.
-Electricity from circuit breaker to upper thermostat is good.
-ECO reset button is not tripped.
-You do not have overheating event.
-Access doors and insulation are in place and thermostat not exposed to cool temperature that causes overheating.

That leaves following suspects:
1) Check if TP valve is stuck open, or pipe cracked, or faucet leaking and running hot water down a drain.

2) Upper or lower thermostat is bad.

3) Lower element is bad -and- maybe tank has built-up sediment

4) Loose wire. Open covers and inspect. Tighten screws very tight against copper wire.

5) Bad wire between upper and lower sections of tank.

6) Do complete 30 minute troubleshoot before replacing any parts.

slow leak from what appears to be some kind of adjustment screw on top of pump , solution to stop leak

This is probably just the plug that is used to prime the pump if it looses it's prime, but I can't be positive since your description is a bit vague. I suppose that if you thought it adjusted something that you would be reluctant to just tighten it. Go ahead and tighten it. If it still leaks, then do the following:
Get some teflon tape (ask for it in the plumbing section at home improvement store or hardware store - $2 or less) Get a helper (a child will do). Turn off the power to the pump. Turn on the water at the kitchen sink until it stops running, then turn it off again. Now remove the leaking screw. Some water will come rushing out, but have your helper push his/her thumb over the hole (don't put a small finger IN the hole). Wrap the teflon tape around the screw in a clockwise direction as viewed from the bottom of the screw. Wrap about 5 layers, nice and snug. Don't leave a loose end that will dangle from the bottom of the screw. Put the screw back in the hole, nice and tight. Good luck, Al K

chain came off ,need to know how to put it back on!!!

On the chain saw there should be a panel held on by two screws or nuts where the bar and chain is attached. Remove the two screws or nuts and the panel and you will expose the chain and sprocket. Loop the chain around the sprocket and bar. Put the bar with the chain around the sprocket back on the saw, reinstall the cover with the two screws/nuts, but do not tighten too tight.(You will want to be able to move the bar with the chain.) Then pull the bar away from the saw to tighten the chain, once the chain it tight, then you will retighten the screws or nuts to lock the bar and chain in place. Be sure you lube the chain and bar with "Bar Oil" before starting to put the saw into service. Good Luck...I hope this helped Please rate me, Thanks
