    I have mentioned the list of no. of flashes and their solution:


    ONE Blink--- not used for the self-diagnosis

    TWO Blinks---B+ over current protection (OCP) , unit goes to the standby

    mode then displays the 2 blink fault. Could be a short in the power supply of

    any of the circuits.

    THREE Blinks---B+ over voltage protection (OVP), unit goes to the standby

    mode then displays the 3 blink fault. This is also a problem in the power

    supply circuit, check T603 and R672.

    FOUR Blinks---No Vert. Deflection (V STOP), Screen goes to a single

    horizontal line then the video signal muted. Check IC1509, Q1505

    FIVE Blinks---AKB circuit (AKB), the timer/standby indicator blinks for about

    30 seconds then goes to the self-diagnosis function. Something is wrong with

    the video. Check video out, Q705, 732, 761 and other components on the C

    board, also check Q218, 219, 220 on the A board. Also unit be in IK blanking,

    try turning up screen slightly.

    SIX Blinks---No Horizontal (H STOP), no raster, goes to the blinking selfdiagnosis

    function immediately. Check C515 & 516 and the jungle IC, IC206.

    SEVEN Blinks---High voltage shutdown. The high voltage has exceeded 33k

    and the unit goes immediately into safety shutdown. Check power supply

    regulation and horizontal circuits.

    EIGHT Blinks---Problem with the audio (AUDIO), unit goes to standby and

    blinks the self-diagnosis code. Check IC406 audio amp, PS401 and 402.

    Intermittent problems ?? This is a great feature. You can also bring up

    these fault codes ON-SCREEN to see a list of the problem numbers with the

    abbreviation of the problem and the number of times this problem has

    occurred. This is slightly different than entering the service mode. To see the

    diagnostic screen, Press the following buttons:

    Display, Channel, 5, Vol Minus, ( Not plus ) then Power. This brings up

    a screen with a list of the problems and number of times they have occurred.

    Each of the problem names is abbreviated as, "OCP", "OVP", "V STOP", ETC.

    We have repeated them in parentheses in the text for the "Blinks" described

    above so you can correlate between the diagnostic screen and the blink

    codes.

    So, now that you know about these self-diagnostics, how do you use them?

    Say that you have a set with a black screen. You see that the LED is blinking

    4 times....This would tell you that you have no vertical and that is why the

    video is muted. If it was blinking 6 times, you would know that you have a

    horizontal fault.

    It's not a sure cure, but it's a little better than a poke in the eye with a sharp

    stick.

    IMPORTANT: after you repair the unit, PLEASE clear the values on this
    diagnostic screen. These codes do not reset themselves after the fault
    is 0 corrected, so if you don't clear them, you'll be seeing "old"
    fault codes the

    next time you enter this screen. Clearing is done by going into the
    service mode ( display, channel, 5, volume plus, then power ) then
    press 8 and Enter, which of course returns

    everything to the factory preset condition.

    is it possible to turn tv on manually? if it is, problem is with remote
    control. if it isn't, i would bet its a problem with power supply. Get
    out your DMM and measure the voltages in the
    power supply. if it is too high, tv will not turn on.
    I strongly recommend you to get it repaired.

Hi-

Did you check the fuse on the TV? try plugging it on a different power supply as well.

Trips breaker


tripping breaker indicates over load or dead short
it could be from failed start /run capacitors on the compressor unit ( (most likely)or from vermin across the power board
I suggest that you have a technician inspect and quote on repairs

Compressor builds to 100 lb pressure. after a few minutes use, it comes on again to begin pressure build up. next cycle, it trips circuit breaker in house.


You didn't provide all pertinent info available to you. Lets take what we have; and, consider why your compressor is overloading the circuit breaker. Points to ponder:

  1. Not knowing the exact model (not series) I don't know what the amperage pull is for your "extreme" compressor or the circuit breaker's rating. A 25 amp compressor connected to a 25 amp breaker could be an issue. Campbell Hausfeld's support pages are crashing so I can't check the possabilites.

  2. Are you using a lightweight extension cord? The lower the rating of an extension cord the higher the amp pull on the breaker. If you eliminate the extension cord does the problem go away? Ohm's Law applies. <http://www.ohmslawcalculator.com/ohms-law-calculator>

  3. What else is on this breaker? Is there other high-amp equipment in another room (water cooler, window air-conditioner, portable electric heater, etc.) pulling from this same circuit breaker.

  4. Is the circuit breaker not performing to specification? I've seen failing breakers trip early.

    First, check the owner's manual for power requirements. Next step, use no extension cord; and, insure nothing else is pulling power on that breaker. Then, use a different breaker and see if the problem follows the compressor. If all else checks out than I'd consider binding in the compressor causing the amp pull to be too high.

    Good Luck!

What causes caravan aircon to trip circuit breaker on start up


My first guess would be that the compressor has seized. If not the compressor seizing, then I would look for a short to ground in the wiring. If you pull the cover of the AC you will most likely find that the compressor motor is plugged into a receptacle. If you can unplug or otherwise disconnect the compressor motor from its' power source and activate the thermostat to run and the circuit breaker does not trip, it is the compressor motor. If the circuit breaker trips, then it's in the wiring.

Frigidaire Fas297r2a has power but won't turn on


Hello Chris - Here are a few simple troubleshooting tips that may help you resolve this issue:

· Check the power cord connection to the wall outlet is secure.

· Make sure that the house circuit breaker has not tripped.

· Try testing the air conditioner. Make sure the unit is turned off, Press the TEST button, you will notice a click as the BUTTON pops out. Then press the RESET button. Again, you will notice a click as the button engages, now turn unit on. If the LCDI plug does not reset the cord may be damaged.

· The "Cool" circuit has an automatic 3-minute compressor time delayed start if the unit is turned off and on quickly. This prevents overheating of the compressor and possible circuit breaker tripping. And the fan will continue to run during this time.

· If the unit has been turned off and on rapidly or if the thermostat was changed to a lower number and then immediately turned back to a higher number the compressor may not start. You must turn the unit off and wait a minimum of 3 minutes for the unit to equalize before restarting.

If these assessment measures prove to be ineffective, I would strongly suggest contacting an authorized service technician who would be better able to assist you in the diagnosis and repair of your unit. You can often locate an experienced technician in your area by going to the manufacturer website.

I am having Sanyo room AC model SA185 DX6. The AC was working when all of sudden it stopped working. I checked & found Circuit breaker had tripped. I turned on the Circuit breaker and started again,...


Hello, sounds like the compressor is shorting to ground, this means that one of the windings is making contact with tje shell of the compressor and making the breaker trip. The only option is to replace the compressor, you can check the windings by taking the cover off the compressor which holds the terminals, make sure the unit is unplugged and take one meter lead to each terminal and the other lead to a ground such as a screw you should have no resistance if the compressor is good, if the compressor is bad you will read resistance.

The 2 pole cct breaker is it 2 seperate circuits controlled by a single switch. What is the point of 2 poles?


A 2 pole circuit breaker is for 240 volt appliances such as ranges, dryers, water heaters, large air conditioners, and some motors. The breaker is designed so that _all_ conductors are de-energized when one turns OFF the breaker, or it trips due to overload or short circuit. If one used two individual breakers to supply a 240 volt load (which is not permited by National Electric Code), one could turn OFF just one breaker and render the equipment nonfunctional, yet the other breaker would still be supplying 120 volts to the equipment. Anyone working on that equipment, thinking that the equipment is turned OFF because it's not functioning could be killed by that energized 120 volt line under the right conditions. That's why it's important to always check for voltage on equipment that has been "turned OFF".

Keeps blowing the breaker... only 6 months old


This compressor is small however like other brands in this size range draw 13 - 15 amps. Thats quite a bit of power. The compressor has a thermal breaker that will begin to trip if compressor is hot. I am assuming that the breaker that is tripping is the one on the compessor. I have seen many hitachi breakers fail. Easy to replace with generic 20 amp, cost about $10. Before you replace anything, check amp draw with meter, if within specs try to determine what is causing heat.
example:
cycling too many times per hour (check manual for recommended)
low power due to weak circuit or extension cord
using generator for powering compressor (not recommended)
using low quality oil (use synthetic if hot climate)
air leaking from intank checkvalve back to pump
If no reason to overheat then replace breaker on compressor to 20 amp but watch for overheating. Good luck

Central air conditioner doesn't turn on... Any suggestions?


If the compressor turns off and won?t come back on during a very hot day, the unit may have built up a high "head" pressure and the high-pressure limit switch may have tripped. This is usually located right inside the access panel on the compressor unit. Simply push the button to return it to operation. If your central air conditioner doesn't go on automatically: 1) Be sure the thermostat is set to "cool" and set below room temperature. 2) A central air conditioner should be on a dedicated 240-volt circuit; check the main electrical panel and any secondary circuit panels for a tripped breaker or blown fuse. If you find the problem here, reset the breaker or replace the fuse. 3) Make sure the furnace power switch is turned on and that the outdoor condenser's power switch, mounted on the outdoor unit, hasn't been shut off. Also be sure the 240-volt disconnect next to the compressor (in a metal box, usually mounted on the house wall) hasn't been shut off. 4) Turn off the power to the air conditioner and check the thermostat. 5) Remove the thermostat's cover and unscrew the wire from the Y terminal. 6) Turn the power back on. 7) Holding the wire by its insulation, touch the bare end to the R terminal and hold it there for about 2 minutes. If the compressor kicks on, the thermostat is faulty; replace it or call an air conditioning technician. If the compressor doesn't go on when you hold the two wires together, turn the power back off and call a service technician.
