The database did not find the text of a page that it should have found, named "What could be the problem if a Teledyne-Laars pool heater's pilot light was lit with no problem the valve is 'ON' but the burner does not start up". This is usually caused by following an outdated diff or history link to a page that has been deleted. If this is not the case, you may have found a bug in the software. Please report this to an administrator, making note of the URL. On the inside of the heater cover, and within the documentation shipped with the heater, there should be a diagram of the control circuit. These heaters will not operate if the pump is off (pressure switch), if the "fireman" switch is off (a switch generally inside the pump timer that disables the heater about 15 minutes prior to turning off the pump), nor if both of two additional high temperature limit switches are activated (models will vary). The fact that the pilot is lit indicates that the pilot generator is OK. If you can turn the burner on by shorting the control circuit manually (using a jumper wire) the problem is in one of the safety limit switches or in the thermostat itself.

Also, when was the last time the filter was cleaned?
