Garage Door motor

[asalcedo]

I have an Everest garage door at home.

It has stopped responding to the remote control or the wired switch.

Most likely the motor is fine, and it is just the board with the electronics that has failed.

The Everest engineer has seen the door and has told me that they replace the whole motor assembly, with two new remotes. At a cost of ?1060, which seemed to me extremely high.

The door is small, about 2.10 m wide and 2 m tall.

I have seen at 'Hormann Automation'

looking motors for a quarter of that price.

I am willing to purchase one and install it myself.

Is this easy to do?

What is the best brand?

Are they all the same system?

I can post a picture here. As far as I can see, my motor has a belt like the ones in the pictures (Hormann motors, show it more clearly)

Thanks,

Antonio

just a bit. A backstreet electronic repairer should be able to sort it for far less than 250, let alone 1060.

For you? who knows

No

No one can say for sure. But there are plenty of complete retro fit garage door openers out there for a lot less than that.

Such as this for example:

What the Everest man really means is:

"Everest can't be bothered to stock many spares so they only stock major units. We also can't be arsed to train our fitters to change small parts. Anyway, we can tell our customers that it is better to have a completely new unit as you never know when something else might fail."

Fuse? Check any on the unit as well. Any little lilghts that should be on or blink as the remotes or wired switch are operated?

What a total waste of resources, assuming that they go to the dump. I rather expect them to go back, get repaired and be sold again "new" units.

I also expect you got the door installed with a whacking great "discount" provided you signed up there and then.

At £1060 I'd be having the covers of and fixing it myself. If it's just "dead" I'd be looking at power supplies first and establishing it has what it needs to live.

[Dave Liquorice]

Having a stock of parts across the country or a mechanisium to get them where required in a timely manner costs money. Haveing a repair depot with all the parts required and a handful of "skilled" repairers so that refurbs can be sold as new is another matter,

Yep, anything above normal installation proceedures will add costs.

If I get told that it reduces any faith I had in the kit to almost zero and opinion of the company changes to "will not recomend".

[asalcedo]

The fuse is fine. The leds seem to be fine.

No apparent faults or burnt signs.

The unit was working perfectly well, next day, when I operated it (nobody else did before me), it just stopped responding, with no noise or abnormal sign.

I am going to try to install a new motor myself.

Does anybody have an opinion about which brand I should purchase?

Thanks,

Check there isn't an anti-theft interlock first. The door I have has a pawl that drops into a hole if someone tries to force the roller door up manually, thereby stopping further movement of the mechanism, including by the motor. It can be released using a separate non-obvious mechanism to lift the pawl, allowing the motor to run as normal.

The motor drive fuse doesn't blow because it's stopped by the same mechanism that detects an obstruction when operated normally.

[meow2222]

Would it not be sensible to diagnose the problem first?

if voltage appears across motor, guess at buggered carbon brushes if voltage does not and fuse OK, guess at stuck relay/burnt electronics.

[asalcedo]

No voltage detected at the motor, fuse OK. Something else is the problem, likely the electronics, and I can't get a spare part replacement from Everest.

I have ordered the Marantec Comfort 260, 'Marantec Comfort 220.2 Automation Electric Motors'

The supplier says it should take me no more than two hours to install it.

[meow2222]

Its been years since I looked inside one. The wired controls don't require electronics, just basic switching: a transformer so it switches at lv plus relays. If the fault is in that lot it should be simple to find & fix, though too late now.
