It will be almost impossible to repair a digital board. Will be better to replace it rather than trying to repair.

Our intertherm furnance is clicking twice before the burner lights. Why?


If your unit has a spark igniter you'll hear clicking noises until the flame is lit. If it hasn't done this in the past, then its quite possible the igniter is starting to oxidize and needs to be cleaned. The best way to do this is use a light abrasive cloth to remove the oxidation, or otherwise known as soot. Sometimes, the igniter needs to be removed and as always remove power to the system before attempting any repairs.

LG 42CS460 THE SCREEN HAS TURNED A RED COLOUR


sounds like a problem with the color circuit in the set, possible fix: Problem is that the connectors for the ribbon cables to the mother board are getting oxidized. All of the ribbon cables have to be removed and the prongs cleaned off. That cures the problem! I tried to do it myself but there were too many screws and panels, so I took it to a local TV tech and told him what to do and he did for $48. He said they all showed various degrees of oxidation but the main one was the worst, so it made sense that it was impacting the color image.

Why 2002 Chrysler voyagers have body paint oxidation & when did the paint oxidation start and how can I be reimbursed for the repairs?


this has been a problem since the 80`s and it was caused by the top sealing clear coat not being mixed properly or the wrong/inferior clear coat was being used and not enough applied when the car was being painted. manufactures felt any where they could save a penny was more in their pocket. it affected some cars and not others for some reason and no they do not feel responsible for the problem.

How can I fix my Jura Impressa z5? I have an error 4 on the display of my Jura Impressa Z5 coffee machine and other than turning it off at the power it won't do a thing.


Error 4 is in Plain text a Temperature measurement error in steam cycle (circuit)

Causes / Remedy:

Sorted in order of likeliness !!!

1) Thermal sensor is defective. Determine the resistance value at 20 degrees C to be about 12kOhm. - Replace thermal sensor if not.
OR
2) Cable broken to the thermal sensor or oxidized contacts. - Replace / repair the cable.
OR
3) Logic board defective - replace electronics / replace EEPROM.

If you want to do the job yourself. Parts for repair solutions above are
1) Replacement Thermal Sensor with cable GBP 19.99 plus postage
2) if you can fix broken wire or oxidized contact no need for parts
3) logic board GBP 198.99 plus postage (there might be the possibility to have EEPROM on the board replaced at a fraction of the price. Defective board must be sent in first.

It also is possible to sent in the machine for repair.

I don't know why you would want to make the stuff, you can buy it already made into boards. A couple web sites here for you to check out, one is a supplier and the other is a lot of work if you ask me. Check it out.

Runs intermittent faults F-70


The Duet washer is a good machine, just unfortunate Whirlpool engineers used oxidative circuit board coatings. All the circuit board connections are oxidizing causing the machines to have faulty connections. We have fixed the problem using this information.
UNPLUG the machine first . Take the top off (3 screws in the back) , remove the mother board box from the frame housing and remove the lid. Now you can see the circuit board.
Carefully remove ONLY one (clip plug-in) at a time. Scrap with a (knife or sandpaper or steel wool ) the edge connector where that plug was, on the circuit board removing the oxidated metal (it may not look oxidated but must be cleaned), Next put ( vaseline or mineral oil) on the edge connector where that plug was, NOTE: Vaseline or mineral oil is a non-conductive oil and will not effect electronic operation but will prevent further oxidation and the erratic operation of the mother board will cease.
Now do the next plug and repeat until completed.
NOTE: We recommend only one plug at a time so you do not get confused where each plug belongs.
Put the cover back on the mother board box and reattach to the frame, then put the lid back on and screw it down. End of any problems.

F06 error


"F06" is a motor speed error. The following link explains how to diagnose and troubleshoot:

http://www.fixya.com/support/r714929-f06_error_whirlpool_duet_kenmore_elite

I would first determine is the motor windings are good, then take voltage readings on the MCU. In general, the most common failure is the MCU. That is not to say that this is your problem. You need to follow the recommended advice provided in the link and rule out all possiblities. I hope you find this information helpful. Let me know if you require additional assistance.
