Hampton Bay Patio Heater Won't Ignite? Work Through This in Order

You push the ignition button. Nothing happens. No click, no spark, no flame. Or maybe there's a click but the heater still won't catch. Before you order any parts, work through this in order — the right sequence tells you exactly what's wrong before you spend a dollar.

Quick Answer

Start with the AAA battery inside the igniter. Then try lighting the heater manually with a long lighter. If it lights manually, your igniter is the problem. If it doesn't light manually, the igniter is fine — you have a gas or safety system issue instead.

Step 1: Check the Igniter Battery

Every push-button igniter on a Hampton Bay, Master Forge, or Gardensun patio heater runs on a single AA battery inside the igniter housing. When that battery dies, you get no click and no spark.

Find the igniter assembly on the heater — usually a black plastic housing near the control knob or burner head. Look for a small cap or compartment that opens with a coin or screwdriver. Swap in a fresh AA battery and try again.

If you now get a click and a spark — try lighting the heater normally. If it lights, you're done. Dead battery, no parts needed.

If there's still no spark after a fresh battery — move to Step 2 before replacing anything.

Step 2: Try Lighting It Manually

This is the most important diagnostic step and most people skip it. Before replacing any part, try lighting the heater manually with a long-reach lighter or fireplace match.

Turn the control knob to the pilot position and hold it down. Use the lighter to reach the pilot opening and light the flame directly. Hold the knob for about 30 seconds, then slowly turn it to your desired heat setting.

If the heater lights and runs normally with a manual light — your igniter is the problem. The heater itself is fine. Gas is flowing, the thermocouple works, everything is good except the electronic igniter. Replace it and you're done.

If the heater won't light manually either — the problem isn't your igniter at all. Skip to the "If It Won't Light Manually" section below.

Step 3: Replace the Igniter

If the manual light test confirmed the igniter is the issue, here's what to do. First check the spark gap — the electrode tip inside the burner should be positioned about 3–4mm from the metal target. If it's bent away or corroded, try repositioning it and cleaning the tip with fine sandpaper. Sometimes that's all it needs.

If the gap looks fine but there's still no spark, the piezo mechanism inside the igniter has worn out. Replacing it is one of the easier repairs on these heaters — two screws, swap the assembly, done in under 10 minutes.

We carry OEM igniters for the most common models:

In the meantime, keep using the heater with a manual light until the replacement arrives.

If It Won't Light Manually Either

If the heater won't light with a long lighter, the igniter isn't your problem — something is wrong with gas flow or the safety system. Work through these:

Check the Tank

Is it actually full? A tank that feels light or hasn't been refilled recently may simply be out of propane. Try a fresh tank before diagnosing anything else.

Check Gas Flow

Turn the control knob to pilot and hold it down — can you smell gas at the burner opening? If there's no gas smell at all, the issue is upstream of the burner. Check that the tank valve is open and the hose isn't kinked or damaged.

Clogged Pilot Orifice

After sitting in storage over winter, insects and debris occasionally clog the pilot orifice. With the tank disconnected, give the pilot opening a short blast of compressed air to clear any blockage.

Thermocouple or Tilt Switch

If gas is flowing but the heater lights briefly and then shuts off — that's a different problem entirely. That's the thermocouple or tilt switch, not the igniter. See our guide on heaters that won't stay lit.

Which Models Does This Apply To?

  • Hampton Bay NCZH-G-SS and all NCZH variants (Home Depot)
  • Hampton Bay HSS models
  • Master Forge tall and pyramid heaters (Lowe's)
  • Gardensun GSH, BFC, and all standard models

Summary

Battery first. Then manual light test. If it lights manually, replace the igniter. If it doesn't light manually, the igniter isn't your problem — you have a gas flow or safety system issue. That simple sequence tells you exactly where to focus before spending money on anything.
