Overload, usually means that is overloaded. i've had the receiver for about 4 or 5 years now and never had problems with it. It was sitting ontop on my tv for those 4 or 5 years, and i haver noticed it untill just recently, (when i bought a new tv and i had to get a stand for it, and i had to stick the receiver in it)that is runs very hot, very quickly; Maybe that is the problem you are having now, that the thins is older and maight be able to handle it as it id b4. Maybe you made some changes to your set up: new speakers, etc.

Sounds like an electrical problem. Check connections to battery remove & clean them , check + wires to engine, to power supply for the engine management.

Error codes


Samsung Washer Fault Codes
4E WATER SUPPLY ERROR Water Supply Error occurs when water level frequency does not show changes more than 100Hz or water is not supplied up to the preset water level after 10 Minutes or more at the time of initial water supply. The error status can be cleared by turning the POWER switch OFF and back ON.
5E WATER DRAIN ERROR 5E is displayed if the water level frequency detected is 25 KHz or less in the initial phase of the UNB -detecting cycle. The Water Drainerror can be cleared by turning POWER SW OFF and back ON.
oE OVER-FLOW ERROR Over-Flow error occurs when the water level is too high. It can be cleared by turning POWER switch OFF. Water is drained prior to POWER switch OFF. The tub is drained for 2 minutes if a frequency of more than 25 KHz is detected.
UE UNBALANCE ERROR Laundry load is unbalanced, manually loosen any tangled laundry.

If only one item of clothing needs washing, such as a bathrobe or jeans, the final spin result might be unsatisfactory and an UE error message will be shown in the display. Unbalance error is cleared by POWER switch OFF and back ON.
HE WATER HEATER ERROR HE, HE1 is displayed if the water temperature rises by 7 C or more in 1 Min or by 2 C or less 20 Min after heating process has started. The error can be cleared by turning POWER switch OFF.
1 E WATER PRESSURE SWITCH ERROR * Generated Frequency Signal of WATER LEVEL (WIL) SIW (KHz)

Normal Level = Abnormal W/L Frequency
Low Level = 30.00 Khz High Level = 15.00 Khz

If the same signal is detected for more than 5 seconds, it is aPRESSURE SWITCH Error. When this error occurs the drain pump will operate for 3 min. and the display will show 1 E indicating a pressure switch error.
cE ABNORMAL WATER TEMPERATURE ERROR e.g. If the water temperature is 50 C or more, during a Delicate or Wool cycle.

At the time of initial water supply, if the water temperature is not appropriate, the display will show cE. This error can be cleared by POWER SWITCH OFF.
11 E WATER LEAKAGE ERROR Water Leakage error occurs when the water drains naturally, (by leakage) after the washing program starts.
tE THERMISTOR ERROR This error occurs when the Thermistor circuit is abnormal or a voltage of O.2v or below or, 4.5v and over is detected. This error can be cleared by POWER switch OFF.
3E MOTOR RESTRICTION ERROR Hall Sensor is sensed every 5OOms. 1 second after motor starts to work.

If data of hall sensor is less than 2 (2RPM), the Washing motor will stop at once.

During Washing and Rinsing when a motor restriction is sensed, the motor stops and then proceeds to the next water -flow action. If the motor stops working and this happens in one direction ten times, "3E" Error is displayed.

During dehydrating. when a motor restriction is sensed. the motor stops working and then returns to the initial stage of the dehydration unbalance sensing cycle. After ten times, "3E" Error isdisplayed, When the motor Is told to stop because of an operating function. no error is shown.

Power 81W OFF can clear the motor restriction error.
8E OVER CURRENT ERROR IPM fault signal (this is caused by the overload of the MICOM INTO during motor action).

IPM: Integrated power module. The IPM controls the motor.

If the fault (low signal) happens to be sensed even once during the washing/rinsing stage, the motor stops immediately. However, during the dehydrating stage the signal is to be sensed, when the number of signals reads more than 6 per 500ms during the Washing or Rinsing cycle action.

If the motor stops working, in one direction ten times, "8E" Error is displayed.

During dehydrating, when the overload is sensed, the motor stops working at once and then feeds back to the initial stage of the dehydration unbalance sensing. When the feed back has occcurred twice, Error "8E" is displayed during the dehydrating unbalance sensing, No error happens by overload sensing. When it happens at more than 800rpm, the process is stopped compulsorily. Power Switch OFF can clear the overload error.

would advise calling a tech... hope this helps.

Problem display with laptop


Hi,

I am giving you some steps, which will help you to determine where the fault lies. In this situation like yours, this is the best I can do. Please come back to me the result and I'll help you to resolve it.


- Whenever the distortion is occurring, fix it to an external monitor/TV (if you have such facility). If the distortion does not occur there, your display is gone.

- Check if the distortion occurs during booting. That is, before any drivers are loaded. You need to look carefully. If not, it may be a faulty driver. Sometimes, drivers malfunction due to conflicts with different applications. This can be an application you have recently installed.

- If distortion occurs during booting, it may be faulty graphics card. To check it further, you can take a bootable CD/DVD and boot from that, and see if the display is correct; if not, the graphics card is gone.

If your graphics card is an integrated one, you can't replace it, but you can send it for repairing.

Hope it helps. Do let me know.



Good Luck & Thanks,
Shiv.

Kenmore AC compressor on and off while outside unit fan running


If the out door fan keeps running and the compressor cycles off that would be the overload in the compressor.
What keeps the windings cool is the refrigerant back to the compressor.
For the overload to cycle it would have to be either not enough cooling back to the compressor or high amp draw, which could be the metering device (txv or orifice) or low on charge, or other things would be a bad capacitor, sometimes a bad start relay not staying open, when compressor gets up to speed or anything causing the compressor to draw high amps.
To check the refrigerant, he needs to check the superheat at the compressor it should be appoximately 12° to15°, and next time the compressor goes off if you shut the power off and feel the top of the compressor and if it's hot 130° or higher it's probably refrigerant.

Overloaded generator


Check a see if it is when the unit is starting up when the over load happens if so you need a hard start kit

Problems Overload Protection Being Invoked - Parasound HCA-2003


You may want to get an Ohm meter and check between the outputs of the amp yourself. 0 ohms means a short somewhere.
You should also check to se when you're hooking the speaker wires in that they're not frayed and touching hot to ground or hot to the amp casing. hope that helps!

Message on screen 8E, Motor won't start on spin cycle. Model no Q1435(C/S/V)


This is what I found:
11. OVER CURRENT ERROR - Display shows 8E .
- IPM fault signal (that is caused by the overload of MICOM INT0 during motor action) is sensed.
IPM : Integrated power module. , IPM controls motor.
- If the fault signal (low signal) happens to be sensed even one time during cleansing/rinsing stage,
the motor stops immediately. However, during dehydrating stage the signal is to be sensed
when the number of signal is more than 6 for 500ms.
- During Cleansing or Rinsing
When the overload is sensed, the motor stops immediately and then proceeds to the next water-flow action.
If the stopping of the motor working is happens in one direction ten times,
"8E" Error is displayed.
- During dehydrating
When the overload is sensed, the motor stops to work at once and then feeds back to the initial
stage of the dehydration unbalance sensing.
When the feed back is continuously happened 2 times, "8E" Error is displayed
During the dehydrating unbalance sensing, No error happens by overload sensing.
When it happens at more than 800rpm, the process is stopped compulsorily.
-Power S/W Off can clear the overload error.
in short: imbalance problem
In a german forum one guy solved the problem by replacing the motor electronics. I am currently experiencing the same problem. I keep you posted.

Overload


That same thing happened to me a few months back and the problem was that the terminals of a speaker were not connected properly, check all of your speaker cables, or check for a broken speaker by setting the volume of each one and make sure they all work, you might find the problem there!!!
