How Many Amps Does A Liftmaster Garage Door Opener Use?

Liftmaster is a leading manufacturer of garage door openers, known for their reliability, durability, and advanced features. Understanding the electrical requirements of your Liftmaster garage door opener is essential for ensuring proper operation and safety.

The amperage draw of a Liftmaster garage door opener varies depending on the model and motor size. Typically, most residential Liftmaster garage door openers have an amperage draw between 13 and 16 amps.

Here's a breakdown of the amperage draw for different Liftmaster garage door opener models:

Chain Drive Openers: 13-15 amps
Belt Drive Openers: 14-16 amps
Screw Drive Openers: 15-17 amps

It's important to note that these amperage values are approximate and can vary slightly depending on factors such as the weight of the door, friction, and operating conditions.

When selecting an electrical circuit for your Liftmaster garage door opener, it's crucial to ensure that the circuit is rated for sufficient amperage to handle the opener's electrical demand. A circuit that is overloaded can trip the circuit breaker or cause electrical problems.

To determine the appropriate circuit rating, add up the amperage draw of all the devices connected to the circuit, including the garage door opener, lighting, and other appliances. The total amperage draw should not exceed 80% of the circuit rating.

For example, if your Liftmaster garage door opener has an amperage draw of 15 amps and you have two lights connected to the same circuit, each drawing 2 amps, the total amperage draw is 15 + 2 + 2 = 19 amps.

In this case, a 20-amp circuit would be sufficient to handle the electrical demand. It's always advisable to consult with a qualified electrician to determine the appropriate circuit rating and ensure safe and reliable operation of your Liftmaster garage door opener.
