Cracked Heat Exchanger Symptoms

The majority of homes will use a furnace for this job. When the heat exchanger inside the furnace cracks, though, it can lead to costly repairs. Here are the most common cracked heat exchanger symptoms.

Cracked Heat Exchanger Signs

A cracked heat exchanger is a serious concern for homeowners because it can create a major health hazard. The heat exchanger is a metal container featured inside a furnace, responsible for collecting hot combustion gas from the burners.

The heat from the gas will transfer to the metal walls, ultimately causing the exchanger to burn hot. The blower’s air will then move around the exchanger, picking up heat prior to it passing into the ventilation system. Any leftover combustion exhaust will be sent out a flue to escape harmlessly outdoors.

However, if the exchanger is cracked even a little bit, the toxic combustion gases (mostly carbon monoxide) can enter into the air that’s blown into the rooms. This creates a serious health concern. Let’s take a look at the signs indicating a cracked heat exchanger below.

1. Corrosion

Corrosion and cracks may occur in many furnace components. This can include the inducer motor or draft diverter box, and this can be a serious cause for concern.

2. Odd Odors

Unpleasant and strong odors can result from a malfunctioning heat exchanger. Typically, the odor will smell similar to formaldehyde.

3. Loud Sounds

When your thermostat turns the heat on, you may hear a distinct rattling noise. This indicates there is a crack in the heat exchanger.

When the metal heat exchanger ultimately is heated, rattling, banging, and popping noises may be heard.

4. Presence Of Carbon Monoxide

It is possible for a failed heat exchanger to leak carbon monoxide into your home. Unfortunately, only a carbon monoxide detector or alarm can make you aware of its presence.

To avoid this potential hazard, it’s always best to have your furnace and heating system inspected yearly.

5. Soot Build-Up

White soot build-up either around or in the burners of your furnace can indicate cracks.

6. Flame Looks Different

The flame should always appear blue. Orange or yellow coloring is not normal.
