Resistor Repairs and Rebuilds

We at Gridcom understand that it is not always necessary to buy a new resistor—repairing equipment can be more cost effective. Our mechanics are experts at repairing and remanufacturing partially burnt-out resistors. This is our guarantee to you: We follow all OEM specifications and quality controls—repaired resistors will leave our premises in almost the same condition as new ones. And according to our satisfied customers, the resistors we rebuild last as long as new units.

Ask us about Exchange Programs we have in place for Canadian customers.
