First of all, when you start the pool heater the first thing that it does (I am talking about Jandy) is to start the Exhaust Fan to evacuate all the fumes...Is this happening????

After it does that, then the igniter glows and usually takes 17 sec before it reaches the temp.... Can you see it glowing through the eye glass???

When it reaches the temp, the Fan start in a low speed, then the gas valve open and is when the Natural Gas or Propane goes into the burners creating Flames.... If this happening???

Then, the flames are sensed by a "Flame Sensor" which if for any reason it does not sensed will shut down the pool heater... have you check the Flame Sensor????

Well, lets say the Flame sensor is fine and the gas ignites and you have a perfect combustion, so after a minute or two the Exhaust Fan is going to work in a high speed to evacuate heat and Fumes, but also it will shut down the heater if it can't kick on giving you an "Air Flow" message in your screen.

Check this and see if that gives you some ideas how to find the problem. If it does not work, I recommend to call the manufacture of the equipment an talk to then directly.

Good luck!

The heater ignites, stays on about 20 seconds and goes off, after starting and stopping 3 times, it displays a service heater light.


It may not be detecting that ignition occurred. There is usually a sensor that detects ignition and if it is not working right the controller tells yo to service the heater. If you call Sta Rite technical support number they may be able to help you determine what device needs to be replaced. I hope this helps.

Your water heater will have a trouble shooting list printed right on it for the sequence lights. Look at the list to see what Two flashes means and that may help you figure out what is wrong. If not, report back here and let us know how we can help you further. Douglas

How can i tell if my toyostove laser72 igniter is working properly after i have removed it from the unit


If the igniter is still out of the heater, it will get hot enough to burn you in just a couple of seconds if you turn the heater on. You can test the igniter with an ohmmeter. If you connect the ohmmeter to the 2 ends of the igniter you should get 10 - 17 ohms if it is good. With the igniter installed in the heater you can put a clamp on ammeter around just 1 of the leads for the igniter and should get between 2 - 5 amps if it is working. You can also feel the cap over the end of the igniter. Turn the heater on and the cap should start to get warm in 30 - 60 seconds but may take longer. Also, if the igniter is not working you will not see any flame after the 3 minute warm up the heater goes through. Of course this could also be caused by a lack of fuel. The quickest way is either the ohmmeter or ammeter and takes any guess work out it.

I have a problem where the heater ignites easily, stays lit for 30 seconds, then turns off, then kicks back up in 30 seconds. Burners look great? Not sure what could be wrong?


If you have a pilot their will be a flame sensor that's part of it. If this is a glow plug start it will be a probe that goes through the fire wall and is just above the burners. When you get flame the electrons align so that you will get a signal back at the ignition control that will let teg heater run. If it dosn't get a signal it shuts down so you don't get a build up of gas. Then it reset's and tries again. What your describing is a bad sensor or wire. Could be carbon build up on the sensor. If you can't find any problems with these you may have a bad ignition control box. First I would check the wire, connectors and probe itself.

Check the air lines going to air pressure switch for cracks or splits. I know that will affect the gas valve but not sure if that is your problem.

IS THERE A SPECIFIC ORDER FOR THE IGNITION COILS WHEN YOUR REPLACING THEM IN A NISSAN SENTRA 2002 1.8 IF SO WHAT IS THE ORDER


My apologies for the delayed response. I am going back to answer - unanswered questions. I have only been on this site for the past 4-months. Questions Posted have exploded (+55%) since joining.
I do not know if you still need this information, but I am answering it either way.

Looking at the engine with the Oil Cap to the left and Ignition Coils to the right.
Starting on the Left and going Right:
#1 Ignition Connection goes first,
#2 Ignition Connection goes second (to the right),
#3 Ignition Connection goes third (to the right),
#4 Ignition Connection goes fourth.
Again my sincerest apologies....
Let me know if this helped, or if you have additional information or questions. Feel Free to contact me at FixYa.com!

The burner comes on but goes out after 2 seconds


Your flame sensor may need cleaning. It is a sensor located in the flame of a burner far right or far left in the burner box. Use a tooth brush or scotch brite pad. Do not attempt to clean the igniter as it will break.
