If my heat exchanger is broken, what do I do?
If your furnace has stopped working, here are some steps you can take to determine the cause. If you’ve determined that your furnace’s heat exchanger is cracked or inoperable, read on for our advice on what to do next.
Can I run my furnace with a broken heat exchanger?
You might be asking yourself what harm a faulty heat exchanger can cause and whether or not it’s safe to run your furnace.
*In short, the answer is that running your furnace with a faulty heat exchanger is dangerous. You must turn off your furnace immediately and call in a professional as soon as possible.
What is a heat exchanger?
A heat exchanger is where the flame from the burner exchanges heat to the air in your home. If it is not airtight, you may get harmful fumes circulating into the air in your home. These fumes could potentially include carbon monoxide, which is an odourless, colourless gas that can be fatal. Symptoms you may experience from carbon monoxide poisoning are headaches, nausea, and unconsciousness. If you detect that there may be a carbon monoxide leak in your home, get outside right away and call 911.
Check your warranty
Some furnaces have an extended warranty on the heat exchanger and your service provider should look into this for you.
If it turns out that your furnace is no longer under warranty, you may want to consider investing in a new furnace as repairing a heat exchanger can be very costly.
