Question about Heating & Cooling

1 Answer

Baxi he 24 solo. Local Gas safe Engineer has replaced pcb, condensate trap, overheat and other thermostat, also igniter/sparker and flame failure sensor, Boiler still intermittently locking out (red light). He's scratching his head, suggest gas valve. Spending too much without resolution, any Ideas?

Sounds like its an intermittent flame failure on trial for ignition. Look for the pilot flame drifting away from the sensor when the main valve opens.

Baxi boiler


Make sure the gas inlet & outlet pressures are correct (manometer) & that the primary air mixture is adjusted correctly. Check to make sure you have 1 square inch of outside air for combustion per 2000 BTU's rating on the boiler.

MY IDEAL LOGIC 30 HAS FAULT CODE L2 ALMOST EVERY DAY SINCE INSTALATION DEC 2010


is boiler still under warranty?
normal warranty lasts at least 2 years
if so get ideal to send one of their engineers out
L2 relates to flame failure
either boiler has failed to ignite
or
boiler has not detected flame once lit

several causes

failure to ignite
ignition electrode/spark generator

failure to detect lit flame
detection electrode/detection lead

blocked condensate pipe
or defective condensate syphonic trap

you really need an engineer to check these components

Baxi solo pfl60 problem. the boiler has for some time been doing this - the fan starts normally when demand is present, then the pilot ignites, then it all shuts down. this happens repeatedly about 6 times...


One thing I would check is the flame sensor. Your boiler may not have this on it but I have seen them act like this before. If you have one I would replace it. Hope this is ofsome help. Thanks

No blinks normal running igniter glows gas comes on wont run


Check for 24 volts across the gas valve when Ignitor is glowing. If no, bad board. If yes, bad gas valve or blockage.
On a call for heat, the 24 volt thermostat sends a signal to the control module. The control module will indicate a call for heat with a light on the control either blinking or remain solid depending upon model. The inducer (exhaust) blower will purge all gasses from the furnace and pressurize a pressure switch. Once the pressure switch tells the module to continue, the electronic ignition will energize and send 120 volts to the igniter. The igniter will glow and you will be able to see it if viewed thru the small inspection port. Once the igniter gets hot enough, it sends a signal to the module opening up the gas valve (24 volts). Either a pilot will come on or the burner tube will ignite then spread the flame to all burners. Lastly a safety sensor will be looking for a certain temperature within a few seconds and the furnace will continue to operate and the room air blower will turn on in a minute or two.

What could go wrong? The unit will not run if there is no signal from the thermostat (bad thermostat or broken wire), the control module does not sense a signal from the thermostat (bad control), the inducer does not energize (bad motor), the pressure switch does not close (blocked vent piping, bad switch, plugged condensate hose), the igniter does not energize (bad control, bad igniter), the gas valve does not open or there is no gas (bad gas valve, broken wire, no gas), the pilot does not light (dirty pilot), the burner does not light (bad burner, plugged orifice, not enough combustion air), the flame does not spread to each burner (bad flame spreader, dirty flame spreader, more bad burners), the flame safety sensor does not detect flame (dirty or bad flame spreader, bad flame sensor, broken wire, bad control), or the room air blower does not energize (bad fan motor, bad control).

Red light blinking continuosly meanig gas valve relay short how can I fix myself - furnance only blows cold air


You will need to check for 24 volts AC to the gas valve after the igniter starts sparking or glowing. If you have it but it does not open, bad gas valve and you will need to replace it. If you are not getting 24 volts after it starts glowing or sparking, you have a bad board.

On a call for heat, the 24 volt thermostat sends a signal to the control module. The control module will indicate a call for heat with a light on the control either blinking or remain solid depending upon model. The inducer (exhaust) blower will purge all gasses from the furnace and pressurize a pressure switch.

Electric spark starter on one of the burner runs continuously


check the spark head on that particular burner first for dirt,they all need to be clean to recognize the flame after ignition and sense the flame to shut off the sparker module after ignition,and if not you will need to replace the spark module that fires the sparkers itself,but try cleaning sparkers and underneath where the wires connect to the sparkers first for contamination,its cheaper than starting to replace parts

Your furnace has a diagnostic chart on the reverse of the lower panel incorporated in the wiring diagram. One blink tells you that it is a failure but wont tell you where to start looking.

FURNACE COMES ON AND SHUTS DOWN WITHIN 15 SECONDS

The inducer (exhaust) blower will purge all gasses from the furnace and pressurize a pressure switch.

When all else fails, check the ground connection for corrosion.
