What should I know about safety edge and photocell repairs in Formby?

Never tape over, bridge or bypass a safety device to make an electric roller door close.
Photocells either side of the opening stop the door closing while anything is breaking the beam between them.
Replacement safety edges and photocell pairs have fitted prices, agreed before the visit is booked.
Photocells can often be added to doors that only have a safety edge, if the control box allows it.

How does it work in Formby?

The engineer tests the circuit and replaces the faulty device, then tests the door. Any further parts are quoted before they're fitted.

Powered door safety

Every powered door we fit is commissioned with force testing to BS EN 12453 and handed over with a Declaration of Conformity and UKCA or CE marking, as the Supply of Machinery (Safety) Regulations 2008 require.

Electrics

An electric door needs a power supply near the roller box. Electrical work must meet BS 7671, and in England some domestic electrical work is notifiable under Part P, so it is done by a registered competent person or signed off by building control.

Safety edge and photocell repairs in Formby: questions

Will you fix the door on the first visit?

A fault can sometimes be found and put right on the first visit, but we never promise it. If a part needs ordering, we quote for it first, make the door safe where we can, and confirm the return date in writing.

Do you repair roller doors you did not fit in Formby?

Yes. We repair roller garage doors of any make in Formby and across L37 and L38, where parts are available. If a part is no longer made, we tell you what will fit instead, or price a replacement door if that is the better option.

Do you cover Formby?

Yes. Formby is part of the area we cover in Merseyside, including L37 and L38. Get a guide price online, then we confirm a survey or visit date in writing. Dates depend on installer and engineer availability.

What should I do while I wait for a visit in Formby?

If the door is stuck part-open, keep people, pets and cars clear of it and switch off the power at the isolator if it is safe to reach. Do not force the curtain or open the roller box. Your Formby visit date is confirmed in writing.

How do I test my safety edge and photocells?

Follow the manufacturer's instructions for your door. In general, the test checks that the door stops or reverses when the safety edge meets an obstruction while closing, and that the door won't close while the photocell beam is broken. Keep people and pets clear while testing, and repeat the test monthly.

Why does my roller door reverse when nothing is in the way?

A door that reverses on its own while closing is often reacting to a safety device that thinks there's an obstruction. Dirty or misaligned photocells, a damaged safety edge, a loose cable or limits that have drifted can all cause it. Clean the photocell lenses and check the beam is clear, then request a visit if it continues.
