Why is my vape lighting up but not hitting?

What this symptom tells you

When the LED comes on, it confirms three things: the battery has charge, the fire button works and the firing circuit is sending power. If you are still getting no vapour, the problem is somewhere between the firing circuit and the coil itself.

The LED firing without vapour is actually useful information. It rules out the most common serious problems (battery, button, lock) and points you toward the coil, airflow or connection.

The five common causes

The diagnostic process

Work through these checks in order. Most cases are solved within the first three steps.

1. Check the airflow

   Look at the airflow control on the tank or pod. Is it fully closed? Open it fully and try again. On pod kits without adjustable airflow, check the airflow hole at the base is not blocked by lint or pocket fluff.

2. Check the mouthpiece

   Look down the mouthpiece. Is it blocked by condensed e-liquid or debris? Wipe clean with a tissue. On removable drip tips, pull off and check the inside of the chimney.

3. Check the e-liquid level and prime status

   Is there liquid in the tank or pod? Is it above the side wicking holes on the coil? A fresh coil needs priming. Let the device sit for 5-10 minutes if you have just installed a new coil.

4. Reseat the coil

   Unscrew or unclick the coil and reseat it firmly. Make sure it connects fully to the tank base.

5. Clean the contacts

   Take the tank off the battery. Wipe the centre pin on the 510 connection with a dry cotton bud. Also wipe the matching contact on the base of the tank.

6. Check the wattage

   Look at the coil's wattage rating. Set your device to the middle of the recommended range. Under-firing a coil produces minimal vapour even when the device is firing.

7. Try a fresh coil

   If everything above fails, the coil itself is the problem. Replace and prime properly.

What “not hitting” can actually mean

People mean different things by “not hitting”. Identifying the symptom precisely helps with the fix.

Special case: auto-draw pod kits

Auto-draw pod kits (no fire button, activated by inhaling) have a different failure mode. The LED on these usually means the device has detected something, but the airflow sensor itself can fail.

• Pressure sensor blocked: Lint, dust or moisture in the airflow channel can block the sensor that detects your inhale. Tap the device on your palm firmly a few times. Wipe the airflow holes with a dry cotton bud.
• Auto-draw threshold: Some devices need a firmer inhale to activate. Try a slightly stronger draw.
• LED flashing without firing: Often signals low battery or detected blockage. Charge fully and try again.
• Pod not seated correctly: Even click-in pods can be slightly loose. Press the pod firmly until you hear or feel the click.
• Inverted use: Some pod kits will not function if held upside down. Try in the normal orientation.

The wattage problem in detail

A coil that runs well below its rated wattage may heat slightly but not enough to vapourise liquid effectively. The result: LED on, slight warmth, but no real vapour.

Practical example: a 0.6 ohm coil rated 15-25W needs at least 15W to function. At 10W you may see the LED come on but get almost no vapour. Set it to 18-20W and the same coil performs normally.
