We are a Robinair Authorized Service Center for Northern Indiana and southern Chicago region, I rebuild and repair the (unavailable anywhere online, including Robinair) RA20070 power control / relay board for the 34788 and 34988 machines. This auction is pretty simple, when you purchase, box up and send me your old RA20070 and I rebuild it using the best Austrian made Shrack components available. I have both a 34788 and 34988 machine on-site to do full output tests of all board functions on, before I send it back. I have a 100% success rate after about 20 repairs now. Each board is verified and tested to 100% factory spec before being sent back to you. 24-48 hour turnaround time. This is to remedy a number of problems, most commonly not recovering or not clearing lines. I pay return shipping. Package them well with good padding. No returns accepted, due to customer installed electrical components, the possibility of a bad power supply on your machine, etc. Hopefully that's understandable. Mail your board to
