Why is My Patio Heater Igniter Not Clicking? [ANSWERED]

A patio heater spark igniter that is not clicking can indicate the spark igniter is out of batteries, the ignition’s wires got disconnected, the owner neglected to push in the control knob, or the igniter itself got wet or damaged.

Make Sure Your Patio Heater Igniter Is the Problem

I’m sure you can tell whether or not your Fire Sense patio heater isn’t lighting up because of the spark igniter, but it never hurts to make sure so that you don’t waste your time, effort, and money on an area that it turns out wasn’t the issue.

Your patio heater spark igniter, also known as a sparker, is a small electrode that is supposed to ignite the pilot light and get a flame going.

The easiest way to see whether your sparker is the problem is to activate your gas and use a different light, maybe preferably a lighter with a long neck, and see if you can start a flame that way.

If you can’t, then there’s another problem with your patio heater such as an empty propane tank. If you can start a fire with an outside flame, your spark igniter is certainly the problem or one of the problems.

Before you decide to preemptively purchase a new sparker, take off the casing around the igniter and make sure it’s giving off sparks. The clicking noise will also indicate sparks.

You Didn’t Push the Control Knob in

According to page 12 of the owner’s instruction manual for your Fire Sense Patio Heater, if it’s your fire sense patio heater igniter not working, it could be because you didn’t push the control knob in BEFORE pushing the red igniter button. This will ignite the main burner. Then you repeat until the burner ignites.

This is a common step you can miss, but the full initial list of steps you should take are:

  1. Turn your control knob to the “OFF” position.
  2. Make sure your LP cylinder valve is fully open
  3. Turn the control knob halfway between the small and large flame symbols
  4. THEN push in the control knob

If this doesn’t work, let the gas disperse for at least 5 minutes before attempting the next suggestion to make sure there’s no flash explosion when you have a successful spark.

Your Lighter is Out of Batteries

The electricity powering your spark igniter has to come from somewhere, and in your case, your Fire Sense Patio Heater needs a AAA battery to start.

If you’re wondering where you would insert the battery, the answer is behind the red ignition button. All you have to do is unscrew the red button with its black attachment, insert your AAA battery with the positive side closest to the button, and screw the button back on.

The ignition problem you’re having could even be caused because you inserted the battery wrong the first time! Most of the time, you’ll find that your ignition issues have very simple solutions.

Your Wires are Disconnected

Your spark igniter is a long tube of wires that is connected to the igniter’s head on one end, and connected to a small black tube which is the push-in connector.

It’s very easy to pull out the bottom end from the push-in connector, and even a good bump can disconnect the wires. If you know your patio was knocked over or got hit by something, consider checking the connection. It will be easy to see where the connection should be.

The Igniter is Wet

This isn’t usually an issue for patio heaters because they are fairly well-protected on top by their wide covers, but if it’s windy enough on a rainy day, or raining hard enough, or the heater is pushed over into some water, then your igniter or the wiring can get wet and prevent the ignitor from working.

Intuitively, you might suppose that starting the flame will dry any wet parts, but that won’t work very well if you can’t get a fire started to begin with because everything is wet.

Instead, take a cotton swab dipped in rubbing alcohol and rub it along the ignition. Not only will this make the moisture evaporate, but it will also clean the igniter’s head of any contaminates that might have been preventing it from sparking.

This might be the problem you’re having if you notice that your clicking and sparking are happening, but the sparks are weak.

You Need to Replace the Igniter

When you have gone through the entire troubleshooting list and the igniter still won’t click or spark, you know that it’s time to replace the igniter entirely. You would also have to replace your igniter if it or its casing is cracked or damaged in any way.

Keep in mind that you can’t get just any spark igniter. If it’s your fire sense patio heater igniter not working, then it’s a fire sense spark igniter you need to get. Once you have your replacement, you can follow the steps below to make the switch.

Make sure the heater is off and the regulator is on

In the cold, it’s easy to rush and start the replacement process immediately but take precautions. You’re messing with the igniter and even though you’re sure it isn’t working, you can ensure there are no unfortunate accidents by switching off the gas.

Gather Your Tools

This is a simple project. You’ll only need your hands, a pair of needle nose pliers, and a small wrench that fits the nut attaching the igniter to the head assembly.

Unscrew the Igniter Head

Using your needle nose pliers, hold onto the nut on the side where the head of the spark igniter is, and with your wrench, unscrew the nut on the other side. After initially getting the nut loose, you should be able to just use your hand. Once one nut is off, unscrew the other.

Disconnect the Old Igniter

On the other end of your igniter’s wiring, it will be connected to a small black tube next to the main pipe. Pull it off.

Install the New Igniter

Before attaching the bottom of your new igniter to the black tube, run it through the holes you just took your old igniter out of. Screw on the nuts on either side of the spark igniter and tighten. Next, reattach the small meal panel that was covering the ignition. Lastly, insert the other end into the black tube.
