Do-it-yourself high-quality chandelier repair with a remote control: device, diagnostics, advice

More and more LED technology is entering the home. She brought unlimited possibilities in the design and lighting of living spaces. The manufacturing company Garlen gained great popularity by creating chandeliers with a remote control. Garlen quickly became one of the leading Chinese lighting companies and remains so today.

Device and principle of operation

Before proceeding with the repair of the chandelier, it is imperative that you familiarize yourself with the device of the lamp. Currently there are usually several options available:

• Lamp with incandescent lamps;
• Lamp with halogen lamps;
• Luminaire with LEDs and LED backlighting;
• Lamp with incandescent lamps and LED backlighting;
• Luminaire with halogen lamps and LED lighting.

Incandescent chandeliers are rare. Widely presented are LED lamps with LED illumination and chandeliers with halogen lamps and LED illumination.

Many manufacturers produce chandeliers with a control panel, but, as a rule, they consist of the same blocks: a radio signal receiving unit and LED control (control controller), electronic transformer for LED power supply (Led Transformer) or similar for power supply halogen lamps.

Manufacturers put LEDs for chandeliers with a remote control with increased reliability, but they still fail. In order not to buy new lamps home, it is much cheaper to repair yourself.

Control controller

The controller is a chandelier control unit. The unit contains a radio module that receives commands from the remote control. Depending on the model, the unit contains from two to seven electromagnetic relays that supply power supply to the required electronic transformers, and thus switch on the various lines of LEDs or lamps.

Electronic transformer

It is designed to power lamps or LEDs. The transformer blocks are outwardly similar to each other, but differ in marking. On the transformer for halogen lamps, usually designed for voltage 12V (volts) and power 20W (watts), there is an inscription on the sticker: input AC 220-240V, output AC 12V 120W. This means that five bulbs can be connected in parallel to the unit.

On Led Transforme for LEDs it is written: model lfr807 (66-80), input AC 220-240V, output DC 5V LED (LED supply voltage - 5 volts). The numbers 66-80 indicate the number of LEDs for which this Led Transforme is designed.

Typical chandelier malfunctions

Malfunctions associated with chandeliers equipped with remote control are characteristic. Major breakdowns that are common:

• Does not respond to the remote control;
• Does not respond to a stationary switch;
• A certain number of LEDs or halogen lamps do not light up;
• Several commands are executed from the remote control and stops responding to commands;
• Does not respond to either the remote control or the stationary switch.

No remote control response

There may be several reasons. Take your smartphone, turn on camera mode, point the remote at the camera and press the buttons. If it works, you will see a bright white blink on the screen. If not, then it needs to be repaired.

You can determine the cause of the malfunction by following these steps:

• Battery check;
• Checking the tracks of the console board;
• Checking and cleaning the contact pads of the board.

You need to open the compartment where the batteries are installed and get them out. Check the voltage of the batteries with a multimeter, if it is below normal - replace the batteries.

If further the light device does not respond to the remote control, take and disassemble it, look carefully PCB tracks, soldering spots - there may be ring cracks around them, if any - solder. Clean the pads.

If the remote control works, then the reason is in the chandelier control controller. Remove the chandelier, take out the controller box, disassemble it and you will see the RF receiver board. Check all the capacitors on the board and the contacts of the rations, it is advisable to replace all the capacitors, since their capacity decreases over time, and they leak. Check the contacts near the photocell, they are often lost, if necessary - solder. Check the Chinese photocell for cracks.

If all the detected problems are eliminated, and the RF receiver does not work, then the RF receiver microcircuit is out of order. Replace IC or buy a new RF receiver.

Incorrect work from the remote control

If all modes work from a stationary switch, and from a distance, the selected modes, and then the light element stops responding to commands, then the problem is in the controller board management. On it there are metal-ceramic capacitors that resemble plump pads - they are the ones that need to be replaced.

Fixed switch malfunctions

If the chandelier is switched on from the remote control and does not respond to the stationary switch, this means that the control controller is in good working order and the electronic transformers too. Otherwise, it would not work from the remote control, provided that the remote control and the control controller unit are in good working order.. It is necessary to take a multimeter and ring all the connections of the switch with the controller unit, having previously de-energized everything. Find the break and fix it.

LEDs and lamps do not light up

If all LEDs are off, then the control controller is not working.. If a certain number does not light up, it means that one or more LEDs are out of order, or one of the two electronic transformers that feeds its line of LEDs. The LEDs are connected in series, and if one burned out, then the circuit is broken, and the rest also do not light up. Check the LEDs. Find the burnt one and replace it.

If halogen lamps are used, check the electronic transformers to which they are connected. Then check the lamps themselves: they are usually connected in parallel and can be easily called with a multimeter. Find the faulty one and replace it.

The lamp does not turn on

If the chandelier does not work either from the control panel or from a stationary switch, most likely the chandelier control unit is out of order. Usually, the chandelier control unit performs its purpose very reliably, but due to voltage drops, the control unit microcircuit breaks down, the conductive tracks on the board burn out. Open the unit by holding the board with one hand. Take a magnifying glass in your other hand, with the help of which you carefully examine the metallized paths for damage and microcracks. Damaged items can be repaired.

Diagnostics and repair of LED chandeliers with a control panel does not cause any particular difficulties. You can save a significant amount of money by repairing the chandelier yourself without the help of a specialist.
