Pilot stays lit but wont fire up - Honeywell Heating & Cooling

needs a new pilot generator

if the pilot stays lit and main burners wont fire you don't need to replace the pilot generator! you have an open safety, poor electrical connection or a problem within the tstat controls

check how many millivolts the pilot is generating. if pilot stay lit and burners wont fire u have a problem with one of the safties, lose wire connection, tstat control

If you have a standing pilot that wont stay lit and you have to keep relighting it, it can only be a couple of things that will do this.
1. Try tighting the thermocouple at the gas valve. (this is a thin copper line that goes from the gas valve and goes to the pilot light.)
2. Make sure that the tip of the thermocouple is in the pilot light flame.
3. Make sure that the thermocouple is clean.

if you have done these and it still doesnt stay lit, buy a new thermocouple.

When you light the pilot lite you have to hold the button down until it gets the element hot enough to stay lit. If you hold down the button and lite the pilot and let it go right away it will go out. What to do is hold down the button and lite the pilot and continue to hold the buttn down for about 45 seconds to a minute then let it up very slowly and you will see if it is going to go out by the flame getting smaller as you let up on the button. If it does start to get smaller conitnue to hold it again for a few seconds and repeat the process of letting it up slowly. when the control element gets to the right temperature it will stay lit then turn your valve to "ON" and the fire will start up and continue to heat the water.

You will need a new thermo coupler to keeep the pilot ight on. It is a probe that touches the pilot flame to sense the the regulator to feed the gas flow. Upon failing it shuts off the gas to the regulator so the unit does not catch on fire. In other words it is a fail safe part that is required

there is a small adjustment screw on the gas valve,turn it clockwise to increase pilot,if that does not work the vent cap on the gas regulator on the back of the unit could be stopped up,remove that cap ,clean out or replace unit can operate without it just fine.If you increase the pilot and it still wont stay lit replace the thermocouple

Blow out the dust from the pilot and reposition the pilot where the flame hits the tip. more
