As more homeowners and businesses embrace the idea of extending their outdoor living spaces with patio heaters, it's not surprising that some units might experience issues with lighting. Often, these problems aren't due to major faults in the heater itself. Many times, the heater was simply sitting idle for an extended period and now needs a bit of TLC to get back to work. In this guide, we’ll walk you through some simple troubleshooting steps before you consider ordering replacement parts for your portable patio heater.

At AEI Corp, we hear concerns like "My A270 heater won't light" quite frequently. While it's true that even the best LP heaters occasionally need repairs, the majority of issues can be resolved with a systematic approach. Let’s take a closer look at how to troubleshoot your patio heater effectively.

Pre-Service Checklist: Simple Steps to Get Your Heater Working Again

It’s completely normal to feel frustrated when your patio heater refuses to light. Whether you’re planning a cozy evening outdoors or a gathering with friends, the sudden failure can throw a wrench in your plans. Before you rush to call for professional help, let’s review a checklist of common issues that might be preventing your heater from functioning.

Is There Enough Propane in the Tank?

Most portable LP heaters house the tank within the base, especially the classic mushroom-shaped models. Disconnect the tank and check its weight to confirm if it contains enough propane. A full tank typically weighs around 40 pounds. If it’s empty, you’ll need to refill it at a nearby gas station, supermarket, or another convenient location.

Is the Tank Turned On?

Many users get confused trying to recall which direction turns the tank on or off, especially if the knob isn’t easily visible. Test both directions to ensure you’ve got it right. Don’t worry—this happens to everyone!

Do You Smell Gas?

When heaters remain unused for long periods, the hoses can dry out and develop leaks. To check for leaks, apply soapy water to the hose and look for bubbles. If you spot any, it’s time to replace the old hose with a new one before attempting to relight the heater.

Has the Gas Line Been Properly Bleeded?

Sometimes, air can accumulate in the LP heater’s fuel lines, making it difficult to light the heater. Depress the control knob in the pilot position for about 90 seconds to bleed the line. It’s advisable to have a fresh LP tank ready to ensure successful ignition.

Is the Control Knob Set to Pilot Position?

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

Is the Electronic Igniter Functioning Correctly?

One overlooked issue involves checking the AA batteries. Even when not in use, batteries can lose their charge over time. Replace the batteries with new ones to rule out this possibility.

Can You See the Pilot Flame?

If the pilot flame goes out once the control knob is released, you likely have a fuel-related issue, such as a leaky line or an empty tank. Inspect the lines and tanks carefully.

Once you achieve a consistent pilot flame, turn the control knob to the "ON" position. The burner flame should appear blue-orange. A yellow or red flame indicates a potential blockage, which may necessitate professional repair.

Next Steps If Your Heater Still Won’t Light

After completing the checklist and addressing potential issues, if your heater still fails to light or operates below par, it may be time to consider replacement parts. Below are some general guidelines to help you identify what might need replacing.

• Fuel Tank: If the tank feels empty despite recent refills, you may need a new one. Keeping a spare propane tank on hand ensures uninterrupted use. Propane tanks are readily available at gas stations and grocery stores.
• Gas Smell: If you detect gas when opening the knob, the fuel regulator or hose may need replacing. Start by inspecting the hose, as it tends to crack and become brittle over time. This is a common repair item for patio heaters.
• Electronic Ignition: If new batteries don’t resolve the ignition issue, the electronic igniter may require replacement. Always double-check your battery stock before purchasing parts.
• Irregular Flame: A lazy yellow or red flame suggests a possible blockage in the burner, fuel regulator, or fuel hose. Addressing this early can prevent downtime and ensure continuous warmth.

Proper storage during the off-season is crucial for maintaining residential infrared heaters and commercial patio heaters alike. Extreme heat and sunlight can dry out hoses, which are among the most frequently replaced components. When storing your heater, disconnect the LP tank and cover it to deter pests. This simple care routine can save you time, hassle, and repair costs.

When to Call for Professional Help

After exhausting all troubleshooting options and your heater remains nonfunctional, it’s time to reach out to the manufacturer. A customer service representative can offer valuable insights into lighting techniques and may guide you through additional diagnostics. In some cases, a professional technician can diagnose the issue remotely or visit your location to address the problem directly.

During the consultation, the technician may identify specific areas requiring attention and recommend the next steps. Replacing certain parts, such as hoses, is often straightforward for homeowners or business owners with basic DIY skills. Alternatively, you can hire a professional to handle the replacement for you. In urgent situations, a full-service technician can be dispatched to restore your heater quickly.
