Blown board. Most in home appliances don't have circuit protectors. That's why the made surge strips. But these won't protect against direct electrical strikes.

My air compressor just stopped working completely,has power to it and can turn the fan so its not seized but was gonna start by checking the reset relay and what appears to be a capaciter. just looking for...


The first thing to check is the thermal protector (circuit breaker). It is a small black button mounted on the housing on the back side of the pump motor. The unit will have to cool down before the button will reset. Usuall causes for the thermal protector to pop are: running the compressor on an extension cord, running the compressor on power lines or circuits that can't carry enough amps to run the motor, or little or no oil in the compressor causing excessive friction and heat buildup. If the thermal protector isn't tripped the next thing to check is the pressure switch. If the springs inside are broke or damaged they won't trip the switch to turn the compressor on. If the capacitor(s) are bad the motor will hum and/or try to turn but not have the power to start spinning.

When home theater is turn on, protector push power is flashed on thee screen. player will not function further. volume level is 9. currently can't be turn down.


Protector means there is a short circuit somewhere in either the speakers, the wiring or inside the unit itself....you can try disconnecting all the speakers and then turning on the unit...if the protector goes away, then you have a bad speaker or bad wiring to the speakers....if the problem stays, then there is a faulty circuit in the receiver itself and will need to be serviced

Is it safe to plug a typical Kenmore kitchen refrigerator/freezer into a surge protector?


Safety is not an issue, the problem you may have, depending on the surge protector, is that when the compressor starts up the amps drawn from the circuit is very high which could cause the surge protector to trip, then the power would be shut off to the refrigerator,NOT A GOOD THING!
Good luck !

Sony KV-34HS420 shuts of and stand-by light blinks


  1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
  2. Unplug the television power cord from the electrical outlet.
  3. Let the television remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
  5. Turn on the television.
If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center.

Does my samsung tv keeping turning itself off because of not having plugged it into a surge protector or is it more a fault with my tv


It is a fault with your power supply module actually inside the tv...take it to a local service center or if its under warranty take it back. surge protectors help prevent issues like this occuring due to damage to the power supply from surges but not having one wont cause these problems unless it has recieved a surge.....in future i would use a surge protector on all your expensive appliances, surges and power fluctuations are very common in mains power i live near the mines and we have power problems all the time!! hope this helps,ben

Surge protectors


Hey Laduell,

Before anything else, it's probably best to explain the differences between power surges and flux. Power surges (also called voltage or electrical spikes) are generally caused by a sudden, massive increase or decrease in the voltage flowing through an electrical circuit. Flux, on the other hand, can be defined as the actual voltage flowing through a circuit at any given time.

Whenever an electrical device turns on, turns off, or changes modes of operation, it can cause slight disturbances or differences in the voltage flowing through an electrical circuit. Exactly how much of a difference is made may be dependent on the type of electronic device attached, though major electronics and appliances will have a larger "pull" than smaller devices, like clock radios. The more devices are attached to the same circuit, the larger these voltage differences may become.

This fluctuation in voltage - combined with other electrical, magnetic or radio frequency interference ("noise") - has been known to cause problems or even damage in some electrical devices. To prevent such damage, many manufacturers may include "noise reduction" or "EMI/RFI protection" features in their surge protectors.

As both Dynex and Monster Cables appear to include such a feature in many of their products, the price difference you are seeing may simply be related to the number of additional features that the Monster Cable surge protector offers, though this cannot be guaranteed.

If you're in doubt about your purchase, I would strongly suggest contacting either manufacturer for more information. Most manufacturers are able to provide you with detailed descriptions of their product features, and one of the two may be able to point you towards an online FAQ if one is available. Dynex's toll-free hotline is 888-305-2204, and Monster Cable can be reached at 415-840-2000.

Hope this helps you out.

Sincerely,
Aaron
Go Ahead. Use Us.

find out why the fuse blew in the first place.the protector is just PROTECTING the main circuits of the receiver.the receiver turns on just to confirm the power circuit is OK.
