Hello, I apologize for my English. I have KRC-1.Reports an error 266, P_15 overheating resistance PM1 or fan. I put a new fan and PM1 is cold and still has an error.
I do not know what is wrong
high temperature pm1

Silly question...but it's easily done!
Is the fan rotating in the correct direction?
You should be able to feel the air blowing out of top/back of the cabinet....if not invert the phases on X1.Sent using Tapatalk 2.

Yes fan blows correctly, and yet my error to overheating. Can not be a bad temperature sensor?

Problem with Powermodul (electronic) or check conection to balast resistor, unplug and plug again (make better contact), Powermodul continously check resistance on this device, I've got similiar problem with it remedy was to make better plug to resistor. Fan gives back signal to Powermodul; is fine or its something wrong with fan. Check Red led inside of box with upper fan.

there are three temperature sensors in the KRC1 controller, two are inside PM6-600 (Looks like a automotive terminal in the heatsink, and other in the board of the contactors), the other one is on the ballast resistor.
I think it is easier to you to replace the PM6-600. I think it will solve your problem.

Hello,
Do you checked the fan under the computer?

Does some one know if is possible a make a jumper on theresistence sensor to check if the problem is on PM6-600?
Or the sensor has a Hearting beat like a fan?
Thankyou!
