Working in the garage earlier with eth door open it put 4 on the display and stopped working after a few minutes without being touched or moving. Yes its all running fine/smooth on the mech side.
This guy has an M2 (same type or compatible brand?) and code 4 indicates overload, sugessting some lube required/corrosion or whatever, ditto pgk's comments. Presumably all rails, tracks, bearings are smooth and clean and lubed and all contacts and limit switches checked? Is there an interpretation for that fault code? Has anyone sucessfully repaired one or got any fault finding info of the unit or circuit board? Needless to say the manufacturer says replace the complete unit at around £300 However it now often will not open, switching the mains off/on resets it and it works but often it puts 4 on the display when it wiil not work. We have a Garador auto M2 garage door closer which has worked faultlesly since it was installed.
