IGBT FAULT ERROR KEEPS OCURING ON DF6 340 IVERTOR INVERTOR HAS RUN 14 INTAKE FANS FOR ABOUT 4 YEARS NO OVERLOADS ARE TRIPPING ETC

F61 - error code. This will trigger if the unit has gone into overload to avoid further damaged to other parts. The common causes of this error code. 1. Output IC - this is the most common caused of the error code. Once shorts happened to this IC, it will trigger the error code. Exposure to high volume and/or running in the long time will caused this IC to shorts and produce an overload.
2. Shorted Speaker - if one of your speakers shorts, error code will appear also. This may isolate by disconnecting the speaker to the set and play the unit *****. If the symptom still there the fault came from the unit itself.
3. Shorted Inputs - inputs connector is also prone to shorts due to frequent bending and pulling. To isolate this from fault, disconnect all the inputs connected to the unit like the aux input, antenna, mic, etc.
4. Faulty power supply - once gone to out-of-regulation condition, the error code will appear to protect the most expensive parts from further damaged.Bad solder joints in this section is also to consider.
5. Faulty Fan and its circuitry - F61 will appear only after a minute of operation not upon powering on the unit. Check the fan if working or not...
Also, check whether your unit is still within the warranty period, because the manufacturer will fix it for free.

You will need to change the overload relay and run relay on the compressor.
Here is the overload relay.
Here is the run relay.

Oop's system error has ocurred restarting..,

OK I am guessing this is a modular drive. Fault 39 is an IGBT fault on phase U and 40 is an IGBT fault on phase V. Unless you are experienced it's best to have a qualified service tech do the repair. However here are my thoughts. The IGBT fault may be caused by a dirty air filter located in the side panel. It's some where around 10" x 12". If the electrical panel filter is dirty you don't get enough cooling. The IGBT's get hot and over temp. causing the above fault codes. Check the filter and replace if needed. Next in top of the electrical and drive compartment is a fan. Make sure it is operating properly. If the fan is not operating again you get no cooling air for the IGBT's. I have seen customers open the panel doors and put a large fan blowing on the drive to cool it. I don't recommend this due to the fact the air is unfiltered and can get dirt into the drive and cause damage!. However some customers have to run and take the chance. There are also other items that can cause these faults. But as I said before determining whats wrong can be very technical. Does the display show any other # after fault 39 or 40 like 39 - 3 or 40 - 2. If so this gives additional info on the fault and tests to perform like checking the ID board or interface board. Good luck hope it's a filter.

1 Check that the unit still has elec. supply. 2 check overload trips to compressor / fan 3 check gas charge (is it leaking and locked out on low gas?) 4 possible pressure switch fault.

Is this happening only now! If it was working OK earlier and tripping now only it may be due to some electrical fault inside the machine.

Switch off all the high power appliances and try the dish washer. If it works you have to check the breaker overall power rating!

If it trips during dish washer ON, the fault could be in the heater circuit of your machine. Heater Insulation would have become weak etc.

Dear Sir,

P1506 error refers to Idle Air Control System Overspeed Detected.
So solution is check your Air control system wires,and check air control speed once again.
If this not solves your problem back with the result,leave a feedback we happy to help you.


Have a nice day

Good luck

Hi Tanja

LE is motor error.

Empty water from inside the machine and try tripping the circuit breaker for a couple of minutes.

If that does no clear the error , then one of the following faults may have ocurred:

Wiring connection broken either bad connector on pump side or on timer control side, or faulty wiring harness.
The hose connected to impeller, or the impeller itself is blocked.
Motor or pump locked.
Faulty timer board.

i have moscon g5 ac drives i want to increase torque of this drive in which parameter i can increase torque.

E4 = Compressor Overload: this code means that one of the safety overloads on the compressor has activated.

Diagnosis: the compressor has both an electrical and a temperature overload device built into it. The thermal overload will trip if the internal temperature reaches 154.4° Fahrenheit. This error can be reset by turning the unit off and allowing cool down before turning back on.

Causes

Blockage in the refrigerant circle,
(a high pressure on the liquid side, over 350 psig, and a low suction side, under 40 psig, indicates a blocked cap tube).
If a blockage is diagnosed, the system must be evacuated, blown back and cleared.
If this is the case
I recommended that a filter/dryer be installed in the vapor line before pumping down and recharging.

Condenser fan not working, if the compressor runs, but the fan does not, the motor or its capacitor may have failed. Repair or replace as necessary.

Compressor problem, if the compressor has developed internal faults, it could simply be starving for oil.
Any other internal problem with the compressor will mean replacement is necessary.

Compressor wiring, if the compressor and/or its capacitor have been wired incorrectly, the compressor could overload.
Rewire as necessary.

Please rate this solution.
