Try This Portable Patio Heater Relighting Checklist Before Ordering Replacement Parts

As more homeowners and business owners embrace outdoor living spaces with patio heaters, it's not surprising that occasionally, these heaters might refuse to light. Often, the issue isn't with the heater itself but rather with something simple that can easily be resolved. At AEI Corp, we hear the same concerns every year—“My patio heater won’t light!” While some heaters might genuinely need repair, many times, the solution lies in carefully following a step-by-step process. Let’s walk through a comprehensive guide to troubleshoot your portable patio heater before reaching out for professional assistance.

Before Calling for Help: A Step-by-Step Guide

When your heater fails to light, it can be frustrating, especially if you were planning an outdoor gathering. Instead of immediately calling for help, take a moment to review this quick checklist. It could save you time and money by resolving common issues.

Is There Enough Propane Gas?

Many portable heaters store the propane tank within their base, especially models with a mushroom-shaped design. Disconnect the tank and check its weight. A full tank typically weighs around 40 pounds. If it's low, you'll need to refill it at a nearby gas station or supermarket.

Is the Tank Turned On?

It's easy to forget which way the valve needs to be turned. If you can't see the control knob, test both directions until you find the correct setting. Don’t worry—it happens to everyone!

Do You Smell Gas?

Over time, hoses can dry out and develop leaks, especially if the heater hasn’t been used for a while. Apply soapy water to the hose and watch for bubbles. If you spot any, order a replacement hose and install it before attempting to relight the heater.

Have You Bleeded the Gas Line?

Sometimes air can accumulate in the fuel lines, making it hard to light the heater. Depress the control knob in the pilot position for about 90 seconds to release trapped air. It’s wise to do this with a fresh LP tank connected to avoid complications.

Is the Control Knob in the Pilot Position?

To ignite the heater, the control knob must be depressed approximately ¼ inch and set to the pilot position. Any deviation will prevent the heater from lighting.

Is the Electronic Igniter Working Properly?

Another common oversight is checking the AA batteries. Even unused batteries can lose their charge over time. Replace them with new ones to rule out battery failure.

Can You See the Pilot Flame?

If the pilot flame doesn’t stay lit after releasing the control knob, you likely have a fuel-related issue. Inspect the lines and tank for leaks or insufficient gas supply. Once you have a stable pilot flame, turn the knob to the "ON" position. The main burner flame should appear blue-orange. A yellow or red flame indicates a potential blockage, requiring further inspection or repair.

Next Steps If Your Heater Still Won’t Light

After completing the above checklist, if your heater still refuses to light, take a deep breath and double-check everything carefully. Rushing through the process can lead to missed details. If you’ve done this and the problem persists, it might be time to consider replacing certain components.

• Fuel Tank: If the tank feels empty despite recent refills, you may need a new one. Keep a spare tank handy to avoid running out mid-use.
• Hose: A gas smell suggests a potential leak in the hose or regulator. Start by inspecting the hose, as it’s prone to cracking over time.
• Electronic Ignition: If new batteries didn’t resolve the issue, it may be time to replace the ignition system. Double-check your batteries before ordering a new part.
• Flame Color: A yellow or red flame indicates a blockage or malfunction. Consider replacing the burner, regulator, or hose to restore proper performance.

For both residential and commercial heaters, proper storage during the off-season is key to avoiding unnecessary repairs. Store your heater in a cool, shaded area and disconnect the LP tank to keep it in good condition. Covering the heater can also deter pests and reduce the likelihood of needing replacement parts later.

When to Call for Professional Help

Even after thorough troubleshooting, if your heater still won’t light, contact the manufacturer or a professional. A customer service representative can guide you through additional diagnostic steps. Sometimes, replacing simple parts like hoses or regulators can solve the problem. For more complex issues, hiring a technician to visit your property may be necessary.
