A local customer in Ashford got in touch because the door had developed intermittent problems with the double-locking function.
Intermittent faults can be difficult to trust because a mechanism may work several times and then fail without warning.
After operating the door myself a few times, I agreed that replacing the gearbox was the sensible option rather than waiting for the fault to become permanent.
The customer agreed and I fitted a new gearbox.
Once installed, I tested the locking system repeatedly to make sure it was operating consistently again.
The replacement gearbox was supplied with a 12-month warranty.
