My spacemaker microwave won't heat food

Do the lights and fans work normally when you press START? Does it sound normal, or does it have a deeper, louder "growl"? The latter case definately indicates a bad (shorted) magnetron, although the HV diode would be shorted (as well, or instead of the mag). In the first case, it's harder to tell without some additional test equipment. I could be the magnetron again, but it could also be a bad relay on the control board. In any case, you probably need to have a professional microwave repairman come and check it out.

Will driving the oil gauge went over to 80 & stayed there the oil level is normal

Sounds like the oil pressure sender unit has shorted out internally or the wire has come off and has grounded itself. If not the latter, you need to replace the oil pressure sender. It looks a bit like a small spark plug but with a black insulation and "should" have one wire attached to it.

When I reset My HP Pavillion 9728ca, it would not turn back on no lights no bells or whistle at all then a few day latter in tuned back on???? Then it happen again but it didn't turn back on until a few...

what does RESET mean. tell the helper that first.
my guess is you mean BOOT?

first take out the relic battery (i bet its old and shorted)
does, BIOS work now, hit the BIOS key? yes/no
does it boot to the hDD, now?

To installed W7, Who's, Microsofts or HPs' latter works other dont.
using CD driver to install w7, that it?
does the CD boot and run and ask all the normal questions?
it takes a good HDD to installed W7.
for a fact.

I test the PC with a Linux live disk or Windows PE live disk
first to see if all is good, then run HDD tests from there.
using HDD test software, (free from hundreds of sources) ask

then install w7, when sure.
battery is out.
power pack ok.
and HDD ok.
only then can it work. (if luckly , )

The check engine light won`t come on toyota corolla 1990 its has a 15 amp fuse and it broke. When I change it and latter the fuse is broke again the fuse control EFI.I think is the ignition or any other...

Like you metnion, sounds like a short circuit somewhere.

I would take it to a mechanic or maybe local auto parts store that can run a scanner and possibly give you a code to pinpoint the problem.
Shorts are tricky to diagnose.

If you can gather a little more info, also how long before the fuse blows?

Samsung will not turn on

Hissing sounds like not being on a station or a different type of hiss? The latter may be caused by a leaking high tension transformer and that wull lose you picture and sound and just hiss. It is also dangerous and can cause a fire i feel you need more localised support from a tech to diagnose this corectly Leave it off just in cae it catches fire.

Question...........Reference cooling Fans

yes, there is usually a relay or two on the circuit board to turn on the compressor and the fan motors. either the points of one or both relays are burned or there might be a burned conductor path on the board. if the latter is the case, there would have to be a reason it burned. in other words, just fixing the burned conductor path wont fix the problem, most likely. unless someone was messing around and shorted something, or moisture shorted something, the latter being pretty unlikely. relays burn with normal use. if it is a relay, you can check and fix it by removing the circuit board (after disconnecting power to the unit first), use a real small screw driver, like for glasses, a soldering gun or iron. remove the relay/relays. they are rectangular usually about 3/4 by 1 inch and black in color, take apart and sand points. one piece cover goes around all 4 sides and the top and youll probably crack the cover getting it off, dont worry, you can fill any cracks with epoxy putty or ......

Power off and on again and then no sound present

i assume pressing the source button on the remote control is how you normally turn it on again, (ie video FM CD etc)

it might be that moving the unit to the cabinite the battery power in the remote ( its not infra red its radio wave thay are not picked up by the fm antenna ) is insufficient to wake it up again,
change the batteries in the remote or try to see if there is some weird reason the cabinet is preventing these remote control radio waves from being recieved by the head unit, try opening the door and bring the remote within a few inches of the head unit and see if it turns on when you pres the cd button.

see how you go from there mate
