Ignites and flame comes up but no hot water coming out
SOURCE: Heater kicks on, but kicks right off
There is a small probe that is heated by the pilot flame. This is called a thermocouple & keeps the gas valve open by generating a small electric current. Most likely the pilot flame is too small, or not heating the thermocouple properly. Either turn the pilot up a bit, or gently bent the thermocouple bracket to put it in the flame a bit more. Do not try to bend the thermocouple itself. If this does not help, a new thermocouple may be needed.
SOURCE: heater trane xe 90 working iregular, set to 70 heats up to 64
Possible problemis due to a thermo-couple that has seen better times. If I understand your system correct I would check that.
Heater must have water before it will fire up. There is a delay relay that may be dozing off. Not a bad thing but should be chk'd by a pool sevice.
SOURCE: after the normal delay period, my heater ignites
flame sensor rod is probably not bad but just has a soot build up on it. take some steel wool or I use a soft brass brush and make the rod shine. DO NOT USE ANYTHING COARSE, if you scratch the rod it will rust, then it is bad
