Why does my GE Spacesaver Profile, Microwave/Convection Oven, model # JVM1490SD003, in my motorhome, make a clicking noise when I start it up? Sounds like a fan hitting something. The noise goes away


Probably is the fan tapping something. Power it down/DISCONNECT power. pull unit and if there is a cover, remove it. look for the convection fan and see if it free-spins. should find spot where it is hitting and could be adjusted.

Haier dryer makes ticking noise


The ticking noise could be either a piece of the belt hitting as it spins around, it could be something stuck in the drum that is hitting it as it turns too, or it could be the electric motor making the noise. Either way it sounds like you may need to tear it apart to see what's going on.

I take it that the 'ticking' noise disappears shortly after the engine is started?
Can you identify where the ticking noise is coming from?

There are 2 noises associated with engine wear:
1. A rumble or 'knock' - maybe a 'tapping - ' noise from the bottom of the engine may indicate that the big end bearings are worn. The knock/tapping noise is caused by the worn big end bearings striking the crankshaft. The noise will often disappear after start up because of the oil finding its way into the space between the big end bearing and crankshaft. A rumble/knock/tapping from the bottom of the engine usually indicates a very major repair in the not too distant future..

2. A ticking noise from the top of the engine suggests a worn camshaft/cam followers or cam shells (bearings) .. usually a worn camshaft.

I'm not familiar with your model of vehicle (I'm in the UK). However, I would add that 'big end failure' isn't anywhere near as common as it was way back in the 70s. I would guess that your ticking noise has something to do with the camshaft. Any half-decent workshop would be able to diagnose the problem within a couple of minutes.

It's a relatively quick and easy job to change an overhead camshaft (I'm guessing your vehicle is overhead cam..). You may have to open your wallet and part with some of your hard earned dollars to join the 'replacement camshaft club' .. Worn camshafts aren't too uncommon.

1970 flh When the throttle is backed off the valves make a tapping noise, is this normal?


Your engine is equipped with hydraulic tappets and they shouldn't make a noise however, a 1970 model had probably got a lot of miles on the entire engine unless it's been overhauled. Even then, a lot of mechanic overlook a few things that would cause that problem.

First let's start by adjusting the valves. Take the plugs out of the engine and raise the rear tire off the ground. Put the transmission in fourth gear and bump the engine over until the front cylinder is at top dead center. Remove the pushrod tubes. Loosen the lock nut on the pushrods and back the off until they are completely loose. Then, turn the adjuster downwards until all the slack is our of the pushrod. Then continue turning the adjust exactly four more complete turns and lock the lock nut. Do the same with the other pushrod for that cylinder. Allow time for the hydraulic units to bleed down until you can spin the pushrods with your fingers. Now, you can turn the engine over.

Turn the engine over until the rear cylinder is at top dead center and adjust the pushrods the same way. Once finished, reinstall the pushrod tubes, spark plugs, put the transmission in neutral, and lower the bike. This should stop you ticking if pushrod adjustment was the problem.

Now, the hydraulic tappet units just sit in the top of the tappets. While you've got the pushrods loose, you can take the hydraulic units out of the tappet. To test the hydraulic units, pull it apart and use mineral spirits to clean all the oil out of the unit. Blow the unit dry with compressed air. Put the unit back together and squeeze it all the way together and hold it for ten seconds. If the center pops back up when you release it, the unit is good. If the unit bleeds down and does not pop back up, the unit is worn out.

Another source of "ticking" in the valve train is the rocker arm bushing and shafts. These wear rather quickly. If they are not replaced, they will make a ticking noise. Other than that, there is nothing that will cause he valve train to tick. Now, you can lose a roller bearing on the cam end of the tappet but it'll make a knocking type noise much more noticeable than a ticking noise. Hope this helps.

Good Luck
Steve

Loud tapping noise from carberator


Is the ticking coming from the mixture control solenoid. Unplug the two pin connector on top of the carb and see if the ticking stops. If it does then plug it back in and leave it, it is normal that it clicks. It is the carb switching from lean to rich and back again.

DVD Player makes a slight "tick,tick" sound during playback


I would certainly take the unit back cause that noise could be the tracking or focus coils making that noise as they are being overdriver. This could cause the unit to fail prematurly. Its not an adjustment that you can do your self, it takes special equipment and disc
