I am having a problem with my pool heather, the electric ignition do not want to come on. Anybody?

Whatt is the manufacturer? Pent Air, Ray Pak,Hayward, Teledyne Larrs, Sta Rite?

If it truly is an electronic ignition, you can disregard the person who answered previously. They don't have thermocouples. There's no standing pilot light.

Or is this a standing pilot with an electronic thermostat? They're all apples and oranges. I'll assume all electronic as nothing else is mentioned.

There are a couple of things to check. The thermostat ought to eneergize the circuit and there should be a faint click, followed by a buzzing or zapping sound. If you hear this, then it's a gas flow problem, the electronics are working. The gas valve may be pooched or a bad terminal connection. You can rule out a bad pressure switch, low and high limit switches and thermostat right off the bat as that sound means that those circuits are closed and all their conditions have been met.

If you're not hearing diddly, then it can be one of the above isn't satisfied or is faulty. Additionally, depending on the make of the heater, it can be the heat fusible link (common on a Teledyne Larrs, they can fry), a power supply issue (breaker is on for the heater?) Internal fuse on the controller box (glass fuse), controller box itself is toast or an igniter that's shot.

Electronic ignitions can be the devil to trouble shoot. You need to get in there with an electrical tester to do it properly and it's all about finding out where the current is stopping. If you aren't familiar with electrics, this is where you hand off the job to a pro. That heater may have been wired high volt and I know from first hand experience what it feels like to accidentally hit a terminal in the confined area of that controller box. Easy to do and high volt (220)really wakes you up.

The delayed ignition control is keeping it out, check also thermo-couple.
