Last week a facility maintenance contractor contacted us about repairing a VERY old Johnson Controls HMI panel for a swimming pool at a local country club. This unit’s push buttons were only working intermittently. No replacements were available from the manufacturer or any of its’ distributors around the country. A used, untested, and no guaranteed unit was found on E-bay for $3000.00! The client certainly didn’t want to pay any where near that amount of money for this old of a unit. When asked if we could repair it…..We told the contractor that we would certainly “give it a try”!
He brought the unit over. The case was cracked and broken into many pieces. Upon examination, all of the unit’s push buttons were just worn out and not working. We found that we had some very similar replacement push buttons in stock. Each buttons case took some grinding and filing with a Dremel tool to properly fit, but they worked! All of the units buttons were replaced and then some serious “body” work was required to be done on the exterior case of the unit. With some epoxy and a lot of technician patience, the unit came back together. Having no way to completely test the unit, we contacted the client and informed him about what we had done to his unit. He picked up the unit, reinstalled it and it worked perfectly! This repair was performed in less than one day, and WELL under the used unit cost.
