Question about Heating & Cooling

1 Answer

I have a Sharp portable room air conditioner model CV-P10NC. The power plug RESET button and TEST button will not click in order to check out the power plug as the unit will not turn on. They did test O.K. at first but the unit would still not come on. Can the power plug back be taken off to check out the fuse inside - or since it is a type of built in circuit breaker maybe it does not have a fuse inside ? The instruction manual states that " This air conditioner uses a fused power plug". The unit was working last night but this morning I wanted to drain the unit by following the instructions so I moved the unit sideways to connect the drain hose and pushed the power button on the unit twice as stated but it would not come on, I tried the remote power button but it still would not come on. It seems that this fused power plug is a weak feature of this portable room air conditioner. Thank you for any information you may be able to give me. --- D.L.

    The manual states "This unit uses a fused power plug." Does this mean it is a regular circuit breaker as it has a test and a reset button on its end - The directions state - Press the reset button, insert the power plug into wall socket, press test button- you should hear a click if circuit breaker is functioning correctly, press the reset button until you hear another click - the circuit breaker is activated. Since all the sudden I get no clicks I imagine this plug type circuit breaker is at fault even though it was working last night ???

The fused9G.F.C.I.) cord you speak of is probably the G.F.C.I. built onto these units by design, can you or someone you know get access inside the unit and :Hot-Wire" the units cord and,bypass the power cord ( Just To Test the Unit)and see if it stays operational then replace bad unit cord if this is it.

    yes, if you press the test button and the breaker doesn't click then the breaker is at fault,another way to test this mechanism is to unplug it from the wall receptacle,then plug it back in, it should NOT power up immediately, until you reset the breaker,that is designed in to all G.F.C.I. connected cord and plug units,incidentally there are no fuses, they call it a fused plug...i.e. fuse/breaker, same difference except that this one is resettable, the fuse isn't.

Got cv-p10nc, exhaust pipe was lost, replaced with other one wich gets hot. The problem is different, the power of blowing after 10-20 minutes becomes low, and overall performance is much less than it was...


According to your problem, your new exhaust pipe may not compatible with your air conditioner. First check that the pipe is clean enough. You may have to clean the machine or it may need a repair. Contact with nearest service centre.

My conditioner Sharp CV-P12LX shuts down after 10 min of operation. A noise is heard in the plug reset switch as well

If you have to reset the plug then its pulling to many amps. If you don't know what else is connected to that particular line (in your breaker box) you might consider using another outlet. Increasing amps. of breaker may not be advisable without consulting an electrician.

We have a portable air conditioner. It keeps

Follow the steps below....

1. Power down the air conditioner using the "power" button on the front
2. Unplug the air conditioner from the wall socket.
3. Hold the front panel "power" button down and plug the air
conditioner in. Continue to hold the power button down as the machine

briefly, etc). There is a "beep" sound at the end of the test sequence,
and the machine will be off. At this point, you can release the power
4. Unplug the air conditioner.
5. Plug the air conditioner back in.
6. Congratulations! You should now be able to operate the air
conditioner normally for another 720 hours, but only if you followed
the instructions above EXACTLY.

Sharp CV-P10NC AC unit it has a puddle of water coming down.

earlier models had a pan you had to empty .. your model has a small pump that is supposed to pump the water out the hot air vent (that goes thru the window} .. since its leaking it is likely that the pump inlet is clogged ... you might have to remove a panel to get at that ... it will be near the bottom of the unit (near the drainage nozzle) ... also check the hose that goes out thru the outside vent .. make sure its not cracked, clogged or smashed ... temporarily you can use the drain nozzle to drain off the water to a lower area (it cant drain up without the pump) ...

Air conditioner has to be reset --E1

If your a/c unit is portable,and E1 code most always is "air filter cleaning time" or" water level to high ".
To reset air filter interval turn unit off at power switch then unplug.Hold power switch down while plugging in....unit will go through a short self check then beep.Release power button after beep.Unit should now be reset.
To reset water level....just drain some.....not all.
Most portables use water for increase leave some in.
