Electrical Parts

Along with bulb issues, there are other electrical components that can cause the tree to not light properly.

Transformers/Adapters

Many Polygroup trees with LED lights include an adapter. The adapter adapts standard 110-120 volt, 60 Hz alternating current electrical power by transforming the electrical power to a lower voltage, direct current source suitable for LED bulbs. Polygroup trees with Incandescent or Surebright incandescent bulbs run on standard AC power and typically do not need adapters and they have regular plugs. Some Polygroup trees with LED lights also do not include an adapter. In some older manuals, the adapters may be referred to as a transformer, in others, it is referred to as an adapter.

Transformers/Adapters are rated by voltage output and current output. For example, the "Adapter UL (2015-2016-2017-2018) Ting-Seng ( 29V - 0.45A )" (#11U112904004) produces 0.45 amps current at 29 volts.  Polygroup's product designers select the transformer/adapter appropriate to power the tree's lighting system. 

Usually, the transformer/adapter plugs into a wall power outlet. Thus the transformer/adapter is the first component in the tree's power chain. Certain Polygroup trees connect directly to the transformer/adapter, other trees include accessories, such as foot pedals or light controllers, that connect between the tree and the transformer/adapter.

Bad Transformer/Adapter Symptoms

No lights

Power goes out on the whole tree when all sections are connected. (This occurs because the tree is needing greater amperage than the Transformer/Adapter is providing to the tree, or there is a problem with the adapter.)

Flickering LED lights

Power goes to some of the tree but not all of the lights are lit, or some are flickering when all sections are connected. (This can occur if the tree is set on a setting where the lights are supposed to flicker, the plug connections in the tree are not all connected properly, or because the tree is needing greater amperage than the Transformer/Adapter is providing to the tree.)

 Makes humming noise

The adapter will make a slight humming noise and the lights will be on, this is normal. If the Adapter is making a loud humming noise that you can hear without being directly next to the adapter, please contact us for a possible replacement.

Control Box / Controller

  Control boxes are the components that determine the display modes of trees that have multiple light display options. They feature a button, or buttons, used to change the light display mode and connect between the tree and the tree’s power supply. Some trees with control boxes also have a receiver inside to operate with wireless remote control. The control box attaches to the tree and acts as the receiver for the wireless remote.

Not all trees include control boxes. As an example, trees that have only one color of lights (IE: Clear only, Multi only) or that have no other functions do not require a control box.

Many trees have a control box that can be completely detached from the tree. The control box has plugs on either end so that it can be unplugged from both the tree and the transformer/adapter. If the control box fails, you can remove it and attach your tree light cord directly to the adapter to see if the tree works. If it does work, there may be a problem with the control box. Please contact us to see if it can be replaced with a new controller. Certain trees, however, have a control box that is hard-wired to the tree's bottom section. If a hard wired controller fails, the entire bottom section might need to be replaced.

Hand-Held Remote Control

 Some Polygroup trees come with handheld remote controls. Please ensure that you have all electrical components connected properly as shown in your manual to ensure that everything works correctly.

Make sure the adapter is plugged into the foot pedal (if included) and then plug in the control box and attach this to the tree lights. The control box is the receiver for the wireless handheld remote.

The handheld remote control itself must have working batteries. Please refer to your specific product manual to determine which type(s) of battery is needed for your remote. Most of our Polygroup handheld remotes use the CR2032 3V coin-type battery, but others may use AAA batteries. The remote comes with a plastic tab that needs to be removed before using the remote for the first time.

If the remote does not work, please open the battery compartment on the back to either replace the batteries or make sure they are properly installed. (+/-)

Foot Pedal

 Foot Pedals are a quick way to turn the lights on and off without needing to bend over or get down on your knees to unplug the tree. Most foot pedals are a simple on-off switch, but some may have the control box for the lights integrated with the foot pedal and will have two buttons.
