Understanding Your Broan 688K Range Hood Motor

The Broan 688K is a powerful, built-to-last range hood, and its motor is no exception. It's essential to recognize that there are two types of motors used in Broan 688K models: standard and high-speed. Each has its unique advantages and may be best suited for different kitchen setups.

Let's explore each type and discuss their idiosyncrasies to help you make an informed decision about your Broan 688K replacement motor.

Standard Speed Motors

Standard speed motors are the traditional choice for many homeowners. They're reliable, easy to install, and less expensive. They usually operate at speeds of around 320 CFM (cubic feet per minute), which is adequate for most kitchens. But they might struggle to remove smoke and grease from heavy-duty cooking.

Standard speed motors are typically used in smaller kitchens or homes where aesthetics are a priority. They're often quieter than high-speed motors, making them an excellent choice for those who value a peaceful cooking environment.

High-Speed Motors

High-speed motors, as their name suggests, operate at higher speeds, usually between 500 to 600 CFM. This increased power makes them ideal for larger kitchens, commercial settings, or homes where heavy-duty cooking is a norm. They’re specifically great for handling intense heat, smoke, and odors from high BTU burners, broilers, or griddles.

However, it's worth noting that high-speed motors tend to be noisier and costlier than standard motors. They're also typically more demanding in terms of maintenance, but don't worry, we'll discuss how to maintain your new motor later on.

Finding the Ideal Replacement Motor

Having understood the two motor speeds, the next step is to find the perfect Broan 688K replacement motor. You can purchase a new motor from authorized Broan dealers or online retailers. Always ensure the supplier is reputable to avoid any counterfeit or faulty products.

Before making your purchase, double-check that the motor's horsepower (HP) matches your existing motor. Typically, the Broan 688K uses either 1/3 or 1/2 HP motors. Also, ensure the motor's amperage is compatible with your range hood's electrical setup.

Installing the New Motor

Once you've acquired your new motor, it's time to install it. The process isn't as daunting as it seems. In fact, with a little patience and some basic tools, you can replace the motor yourself and save on installation costs.

First, disconnect your range hood from the power source. Then, remove the motor housing and proceed to detach the old motor. Ensure you document the process by taking a few pictures or making sketches to aid in reinstalling any removed parts. Once the old motor is out, simply attach the new one following the reverse process. Remember to reconnect the electrical components with care.
