Faulty Gliderol Garage Door Opener / Controller | Can I Fix It?

A subscriber asked if I could take a look at his faulty Gliderol garage door controller. The unit appears completely dead and shows no signs of life. He did replace an IC on the board but unfortunately this didn't fix it? Can I find the problem and repair it?
I'm not an expert, but I do enjoy trying to fix things.

[@Matta1224]

Nice fix Mick! You inspired me to fix a high amps 12V battery charger for my father this week. Was a pain to diagnose as the output was short circuited, and every component going between plus and minus had to be taken off for measurement. Started with witness marks, output capacitors had brown goo coming from them, turned out to be factory flux. Tested with mains and found the schottky diode package was getting really hot, removed and tested fine. With those removed the short was isolated to the output diodes or a 330k ohm resistor. Resistor was of course fine, but both diodes were fried. Luckily found some spares and soldered everything back together, and it works! Biggest hurdle was the big powerplanes with leadfree solder. Ended up needing dual soldering irons just to get things off 😂 Very satisfying repair, so I get why you do this👍 Keep on keeping on!

[@robertmjr7996]

Nice work.

[@BuyitFixit]

Thanks 👍and well done on fixing your battery charger 👏👏👏

[@devin8656]

Just a tip, on hard to read part numbers you can usually use a tiny bit of thermal compound on the component and wipe off the excess to make the engraving more visible as the compound fills the engraved numbers/letters. Obviously this doesn't work with forcibly sanded part numbers but can really help in a pinch with ones that are technically still visible but hard to see. Another great fix!

[@BuyitFixit]

Thanks 👍and cheers for the tip 🙂

[@roy2689]

Sometimes an easy fix is satisfying, a duff diode or bad caps can give a real sense of achievement, more complex fixes are great too until you end up in the rabbit hole..

Expedient troubleshooting and repair, excellent. Still surprised at how adept you are at finding faults so quickly. I thought a cap at first then maybe a diode, you went right to the diode...impressive. Thanks for the video and great fix... See ya soon.

[@BuyitFixit]

Cheers 👍Sometimes it can take me a while and sometimes I get lucky. I guess part of it is knowing the rough area of where the suspected fault lies.

A thing i do to help read components is shine a torch across them at different angles while looking though the scope. Usually find an angle that shows it up clearly.

Very good, another saved from landfill (hopefully). Probably an illusion, the main smoothing cap looked very small and a floating earth wire. Bypass switch, perhaps, for version 2 of your dim bulb. I wonder at what point marketing decided that Gliderol sounded better than Roll-a-Glide.

[@Ea-Nasir_Copper_Co]

Their most recent door opener is in fact the Gliderol Roll-a-Glide. I'm wondering if the issue wasn't marketing but legal; ie. if there was already a company called Roll-a-Glide and Gliderol had to wait until that company changed its name, was bought out, or folded before they could assume the trademark.

[@BuyitFixit]

Cheers, yes I had thought of a bypass switch, but I'd perhaps forget it was bypassed and end up blowing something up 😂😂Yes I noticed that on the silkscreen of the board too 👍

[@handyman683]

Epic fix😊

[@BuyitFixit]

Cheers 👍

[@OktaFierce]

Nice fix. You could measure from the motor output relay connectors to see if its putting anything out when using remote.

[@BuyitFixit]

Cheers 👍

[@russellhltn1396]

When pulling caps to test them, I'd pull the one closes to the rectifier - it's the one that gets worked the hardest and most likely the first to fail.

[@BuyitFixit]

Thanks for that. I've still got it on the bench so I might check those before returning it 👍

[@paulmeynell8866]

Nice work.

[@BuyitFixit]

[@tommiecosmo]

Learn alot from you.

[@BuyitFixit]

Thanks 👍🙂

[@garymucher4082]

Looks like you fixed it. I have to say I was surprised when you removed one of the 220 mfd capacitors and checked it and it was good, that you didn't read the others on that line while you had it out. But really doesn't matter since you did find the culprit part...

[@quantumleap359]

Since the whole parallel group measured about 1300 uf, he surmised the others were ok.

[@tomharris1457]

At some point I may have to get a microscope. So far I have stayed with larger components, but there will be that day...

[@BuyitFixit]

Yes unfortunately most things now seem to be surface mount, and getting increasingly smaller!

[@quantumleap359]

I always have a great day when I see one of your videos Mick! The subscriber pays well, eh? Good job.

[@bills6946]

[@BuyitFixit]

[@Markus-fw4px]

You're not just trying, you are knowing what you do! I really would like to know more about your background. Is this all self taught?

[@BuyitFixit]

See the "About" page on the channel. I wrote a brief history :)

[@bobsoft]

When you remove the diode or any component to check, you can solder one end to the pad you just removed it from so it does not move when trying to check it out of circuit.

[@BuyitFixit]

Thanks for the tip. I actually did that with the two resistors 🙂

[@audibell]

Very good

[@BuyitFixit]

Cheers 👍

[@iantyler4045]

Surface mount components are a backward step in terms of reliability it seems. I've seen quite a few .1 mfd bypass caps going short. Nice video.

[@BuyitFixit]

Thanks 👍Yes I've had that a few times. Once in a Hikvision camera, and on the SSD I repaired on the channel (if you didn't see that one)

[@Johny333-xk9js]

wow nice fix :D

[@BuyitFixit]

Thanks 👍

[@oefzdegoeggl]

You should only use the current limiter for a quick check whether you have a short or not. Ideally, you see a short flash of the bulb while the capacitors are charging. Expect weird behaviour (flickering) if there is PFC. Permanent light means "short". You should not test normal device operation with the bulb in series, as the voltage reaching the device is substantially lower than what is expected and this might cause problems.

[@BuyitFixit]

Thanks for that 👍

[@maicod]

4:25 the famous UK HIGHish mains voltage

[@BuyitFixit]

Indeed 😂😂👍

[@Exciteonium]

The voltage up and down was known as Tripping as the safety circuit shut the PSU down then reset over and over.

[@BuyitFixit]

Yes 👍I've had the same when the bootstrap cap fails and the chip doesn't get enough power to startup properly too.

[@gman7692]

You should consider getting a Peak ESR70 - brilliant bit of kit for the price.

[@BuyitFixit]

Thanks I'll have a look into that 👍

[@wisher21uk]

Nice fix Mick as always you did a fantastic job of fault finding, with reference to your series light bulb make sure it’s 100w or more as I have still had things burn out as i had a 60w, normally on a power supply you get a brief flash and when it’s pulsing you know you’re ok 😊

[@BuyitFixit]

Cheers Gary 👍

[@timd1833]

When you first measured 0.0 ohms on the Schottky diode, I saw the silkscreen with "L2" (Inductor #2). Once you removed the diode, the silkscreen showed it was a diode. The L2 must've been for an adjacent component. 😉

[@BuyitFixit]

Yes I noticed that too. It was a little confusing!

[@zebo-the-fat]

Nice fix, but to me a lot of the soldering looks very suspect (but unleaded soldre always looks crap!)

[@BuyitFixit]

Thanks 👍Yes agree. Sometimes the microscope lighting shows it worse than it actually is too.

[@NicksStuff]

Off-line means "off the mains voltage line", I had to Google that

Hey! I’ve got a broken windshield wiper stalk if you’re interested in taking a look at it. The intermittent wiper function is broken on it. I’ve already replaced the stalk with a new one and it is working again. Let me know and I can mail it over to you for analysis. Cheers! Montana

[@BuyitFixit]

Thanks for the offer Montana, I would think it would be something like a bad contact in the stalk. I don't think there's much in them tbh.

[@SeanBZA]

Would have changed the first 220uF capacitor after the diode, those will fail before the others, as they have a 2 stage LC filter. The first capacitor is likely going high ESR already, and will fail in a few more months, as it dries out. Also with the TOPswitch change the primary side small capacitor, as that is the power for the chip, and when that goes low value or high ESR it pops the chip.

[@BuyitFixit]

I've still got it on my bench, I think I'll check those and perhaps the mains smoothers before returning it 👍

[@SeanBZA]

@@BuyitFixit Big mains ones not really going to fail, the small decoupling cap for the chip itself is most likely to fail.

[@eugenecussen3735]

start dropping hints as to your favourite treats ;-)

[@BuyitFixit]

😂😂😂😂👍

[@simontay4851]

You should still test all the caps, especially the first ones after the output diode. The first ones are the most stressed.

[@simontay4851]

Even though the one you tested was ok, the others could be starting to go bad.
