Too much or too little pressure. Check for air blockage or an ice blockage inside or outside the house. Were flames good color when lit?

I'm having the same issue as the above user with Jandy Lite 2 (which from what I can tell stands for the number of times that you can get this POS to work annually)!

Furnace fires but cuts out after 10 seconds. Yellow lite flashing 2 times continuous. Green light flickers and sfter furnace cuts out gos bright green for 2 seconds and then goes back to flickering.


Since you didnt include Brand and Model number, you could check on the inside of'
the front panel you take off to access the furnace. Most have a diagram of the wiring
and will have an Problem Code list that tells you what those flashing lights indicate.
Good luck and feel free to reply with Brand and Model #

I have a coleman furnace it comes on the electric igniter glows red the gas comes on then the blower starts and the fire goes out it gives 2 different code for this 1 is ignition failure and the other is...


I would have the ignition control board replaced. That is what tells the gas valve to come on and if there is flame or ignition it will keep the gas on if the flame sensor gives the board a signal that the burner is lite. By you shuting power off and on to the furnace it resets the board and it will go through its cycle again.

if it has a pilot, you can follow the pilot tube from the gas valve back to the burner assembly and find it. It may not have one and if this is the case, the air flow switch is supposed to close when the inducer fan comes on . If the flue is clogged, condensation in the bottom of inducer fan(would hear cracking). then after the draft safety switch is closed,the gas vavle will get 24 volts and allow the gas valve to open

Gas furnace wont stay lite


I'm a little confused by your terminology. You are saying you have a pilot lite and electric heat strips? Are you possibly meaning burners? Is the heater running for 2 hours straight without shutting off? how cold is it there? Lastly what temperature do you have the thermostat set at and how close does it get to the temp. before it shuts off?

Laars lite 2 LG or LD Pool Heater- Heater won't stay on


the control module is the problem it allows the heater to come on then turns off power to the gas valve.if you are not getting enough water flow the high limit is turning the heater off then your problem is flow.
