Welcome to our blog! Today, we will be discussing the location of the sail switch in Dometic furnaces. The sail switch plays a crucial role in the proper functioning of your furnace, so it is essential to know where it is located for maintenance and troubleshooting purposes. In this article, we will provide you with a comprehensive guide on finding the sail switch in your Dometic furnace. Let’s dive in!

What is a Sail Switch?

Before we discuss the location of the sail switch, let’s understand what it is and why it is important. A sail switch is a safety device that ensures the blower motor of the furnace is running before the burner ignites. It consists of a small switch connected to a metal sail. When the blower motor starts, the air pushes the sail, closing the switch and allowing the burner to ignite. If the sail switch fails or there is an issue with its location, the furnace may not function properly or might not ignite at all.

Locating the Sail Switch

In most Dometic furnace models, the sail switch is located near the blower motor. To find it, you will need to access the furnace. Start by turning off the power supply to the furnace for safety. Remove any access panels or covers that are blocking your view of the blower motor. Once you have a clear view, you should be able to spot the sail switch. It is usually a small rectangular box with wires connected to it.

Specific Locations

The exact location of the sail switch may vary depending on the model of your Dometic furnace. However, some common areas where it is typically found include:

1. Near the blower motor housing: Look for a small box with wires connected to it on or near the blower motor housing. This is likely the sail switch.

2. Attached to the blower assembly: In some models, the sail switch is attached directly to the blower assembly. Check for a rectangular box on the blower assembly itself.

3. Behind a removable panel: In certain cases, the sail switch may be hidden behind a removable panel. Check for any panels labeled “access” or “sail switch” and remove them to find the switch.

Professional Assistance

If you are unable to locate the sail switch or are unsure about handling furnace components, it is always recommended to seek professional assistance. A licensed HVAC technician will have the expertise and tools to safely locate and troubleshoot any issues with the sail switch in your Dometic furnace.

Knowing its location is essential for maintenance and troubleshooting purposes. By following the steps mentioned in this article, you should be able to locate the sail switch in your Dometic furnace.
