Christmas inflatable not working: how to fix it

Short answer: check power first, then the fan intake, then every zip and velcro opening, then the seams. A unit that half-inflates almost always has an opening left undone or an intake blocked; a unit that does nothing at all is usually power.

Work through it in this order

1. 1

   1. Confirm power is actually reaching it

   Plug something known-working into the same outlet. Check the GFCI has not tripped, check the timer is in an on period, and check the cord connection has not been pulled apart. This is the most common cause and the easiest to overlook.

2. 2

   2. Listen to the fan

   If the fan is silent, it is power or a failed motor. If the fan is running but the unit will not stand, the air is escaping somewhere or the intake is blocked. That one observation splits the whole diagnosis.

3. 3

   3. Check the fan intake

   The intake is a mesh grille on the blower housing. Leaves, snow, packaging material and grass clippings all block it. Unplug, clear it, plug back in.

4. 4

   4. Check every zip and velcro opening

   Inflatables have access openings for the blower and often for internal lights. One left partly open is the single most common cause of a unit that stands up halfway and sags. Walk the whole base.

5. 5

   5. Look for water in the base

   After rain, water pools in the lowest point of the unit and the weight of it can stop the unit standing fully. Unplug, lift that section, and drain it.

6. 6

   6. Find seam splits

   With the fan running, run a hand around the seams and feel for escaping air. Small splits are repairable with a fabric patch kit; a long split along a main seam usually is not worth repairing.

7. 7

   7. Check the internal lights separately

   A unit that inflates but stays dark has a lighting fault, not an air fault. Some units have replaceable bulbs; many have sealed LED strings that cannot be serviced.

The rain problem specifically

'It stopped working after rain' is the most common version of this question, and there are three distinct causes behind it.

1. Water pooled in the base. Fabric is water resistant, not sealed, and rain running down the outside collects at the lowest point. The weight stops it standing. Drain it and it recovers.
2. The GFCI tripped. Water reached a connection and the protection did its job. Find the wet connection — see lights tripping breaker.
3. The blower got wet. The motor housing is weather resistant, not waterproof. A blower sitting in a puddle can fail, and that is usually terminal for the fan.

All three are preventable by siting: put the unit on the highest available ground, keep the blower out of any hollow where water collects, and elevate the cord connection. More in are inflatables waterproof.

What is worth repairing

• A small seam split — yes. A fabric patch kit handles it and takes ten minutes.
• A blocked or dirty intake — yes, trivially.
• A failed blower — if a replacement is available for your brand. Gemmy sells them; many value brands do not.
• A long split along a main seam — usually not. The repair rarely holds against continuous fan pressure.
• Sealed internal LED strings — usually not serviceable.
• Fabric that has gone thin and translucent with UV exposure — no. That unit is at the end of its life.

Before discarding a unit with a dead fan, check parts availability for that brand. A replacement blower is a fraction of the cost of the unit, and it is the difference between a five-year inflatable and a two-year one.
