Model PJ556D will run for a few minutes and then shuts off. Once it cools down it will start back up, but shuts off again a few minutes later.


Hello, Greg.

The most common reasons are the temperature is too high or the ventilation holes are blocked.

Unplug the AC power cord, wait 5 or 10 minutes then turn back on.

There could be dust or the air filter needs to be changed.

Take the lamp cover off the bottom. It's possible that the screws holding the lamp are loose.

Hope this helps.

I have a Rheem Criterion II Gas Furnace that has been acting up the last couple of days. It is model #RGPH-12EARJR. It will cycle on, ignite the pilot, 4 burners light and stay lit from 5-10 seconds then...


Turn off the power to furnace.
on the last burner to light there is a small metal rod in front of the burner. This is a safety called the flame sensor. It is dirty. Unscrew it from the bar ( 1 Screw) unplug the connector wire from it and clean it with steel wool. it will be kind of burnt. Plut back in place and turn on the furnace to cycle.

Coffee Makee shuts down and won't turn back on


It's little computer may be scrambled, or its channels may be clogged with scale. You might try (1) unplugging the unit for several minutes to reset the computer; (2) descaling the unit with a vinegar solution.

My Hp c6180 printer has error masage " Improper shut down"


I had the same problem. Try shutting it down by holding the off button and unplugging it for a few seconds from the back of the printer. Wait a couple of minutes and them plug it back in. Make sure you are connect to a wall outlet and not a power strip or surge protector.


If this doesn't work, hold down the #6 key while cord back from the printer.

Hopefully one of these two would work.

If it doesn't you can go to the HP site and start a chat with a tech who will walk you through a solution.

I had the same problem, and got resolved.

Unit shuts itself off after 10 -15 minutes


Protect mode will kick in whenever a fault is detected.

You get the unit not powering up, and sometimes you hear a clicking noise, that is the protection switch that keeps shutting down the unit.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

Regards.

The Kenwood VR517 home theater system wants to just turn itself off at about 5 minutes of being on. this just started happening this week.


If this unit stays on for 5 minutes, and it appears to be playing normal, a bad speaker could be the cause unless you are using speakers that are not compatible with this unit.

The specs on this unit are 100 watts per channel and require 8 ohm speakers. if you are using speakers that are 6 ohms or 4 ohms, you will overheat the unit quickly and it will shut down. It is not designed to use anything less than 4 ohm speakers.

If you are using the speakers this unit came with, or you know that the speakers are 8 ohms (it should be listed on the speaker where the wires plug in), go ahead to the next step.

The first thing to do is to unplug one speaker, it does not matter which one, just pick one to unplug from the back of the receiver or right at the speaker. If you unplug one right at the speaker, make sure that the speaker wires do not touch together or touch anything else, they must be insulated from anything metal or conductive.

After one speaker is unplugged, turn the unit back on and let it play normally the way it was when it shut down after five minutes. If the unit continues to play for a long time, at least 30 minutes or more and does not shut down on its own, you have just found the culprit causing your problem. Some speakers may sound like they are OK, but still can cause a problem.

If the unit shuts down again after five minutes like before, go ahead and plug that speaker back in and do the same thing with one of the other speakers.

Continue this process until you have isolated one speaker as being the problem.

If you go thru the entire process and it still shuts down, you may have an internal amplifier problem. It can be something as simple as some heat stressed solder joints that need to be reflowed, or it could be a bad amp IC. This unit uses 3 different amp IC's and it could be any one of them or a component in the amp circuit. Sometimes it can even be a power supply failure. In any case, if the above steps do not work, you need to take it in and be serviced. There are no other end user options to perform.

I hope this helps with your problem, if you need more help just ask.

No Heat!


Sometimes too much dust around the heating elements can cause the heater to switch off to prevent a fire. Check for dust build up first. You can try using a can of compressed air that can be found at many electronic stores.
