What To Do About a Warm Dimmer Switch
By Dave Rongey - Summary:|
Why Dimmer Switches May Be Warm or Hot: How to Select the Right Dimmer Switch for Your Light Fixtures.
Warm or Hot Dimmer Switch
We have a dimmer switch that gets warm when we turn it on, the wall even gets warm.
- There are two dimmers on the wall and both get warm.
- Other dimmers in the house do not do the same.
- We remodeled with an electrician several years ago and this has occurred since then.
- Should I be concerned? Call an electrician? It does not seem normal
Why a Dimmer Switch May Be Warm or Hot
- Dimmer switches have electronic components that produce heat and will make the cover plate warm, however they should never get hot.
- If you suspect that your dimmer switch is too warm then make a list of the number of lamps that are being controlled by each dimmer switch, and the watts of each lamp to come up with the total number of watts being controlled.
- There are different watt levels assigned to dimmer switches, and if the number of watts being controlled exceeds the rated amounts of watts then the dimmer switch can get too warm, and this could cause the dimmer switch to stop working prematurely or not work right.
- Most dimmer switches over the standard 600 watt rating will have cooling fins which help dissipate the heat that is produced by the dimmer switch. Also note that when two or more dimmer switches are installed in the same electrical box then the dimmer switch sizes must be de-rated when they are installed side by side or ganged together.
Selecting the Right Dimmer Switch for Your Light Fixtures
- If you have 600 watts of lighting to be controlled by a dimmer switch it may be a good idea to install a 800 watt dimmer.
- The concern is to avoid loading the dimmer switch to full capacity, this way you will keep the heat level lower which will contribute to a longer lasting dimmer switch which will provide a wide range of dimming control for your light fixtures.
