No Heat? Here’s What To Check

When your Luxaire furnace is not producing heat, it can be frustrating and uncomfortable. However, before calling a professional, there are some troubleshooting steps you can take to identify and potentially resolve the issue. Let’s explore some common reasons for a lack of heat and what to check.

Filter Inspection And Replacement

One of the first things to check when your Luxaire furnace is not producing heat is the air filter. A clogged or dirty filter can restrict airflow, leading to insufficient heating. Start by locating the air filter, typically found near the blower compartment or air handler. Remove the filter and inspect it for dirt and debris. If it appears dirty, replace it with a new one of the same size and type. Regularly replacing the air filter can help maintain optimal furnace performance and prevent heating issues.

Circuit Breaker And Power Issues

If your furnace is not producing heat, it’s crucial to check the circuit breaker and power supply. Begin by locating the circuit breaker panel in your home. Look for any tripped breakers and reset them if necessary. Additionally, ensure that the furnace’s power switch is in the “ON” position. Check the SSU (service switch) on the gray box near the furnace to confirm it is also set to “ON.” Addressing any power-related issues can potentially restore heat to your home.

Ignition Failures And Solutions

When your Luxaire furnace fails to ignite, it can be frustrating and uncomfortable. Ignition failures are a common issue that can be caused by various factors. Here are some troubleshooting steps and solutions to help you address ignition failures with your Luxaire furnace.

Cleaning The Sensor

If your Luxaire furnace is experiencing ignition failures, a dirty sensor could be the culprit. Over time, the sensor can accumulate dust and debris, leading to improper ignition. To address this issue, turn off the furnace and locate the sensor. Use a soft brush or compressed air to gently clean the sensor and remove any buildup. Once the sensor is clean, turn the furnace back on and see if the ignition problem is resolved.

Replacing The Ignitor

In some cases, the ignitor of your Luxaire furnace may be faulty, damaged, or worn out, leading to ignition failures. To replace the ignitor, turn off the power to the furnace and locate the ignitor assembly. Carefully remove the old ignitor and install a new one according to the manufacturer’s instructions. Once the new ignitor is in place, restore power to the furnace and test the ignition to ensure it is functioning properly.
