Question about Heating & Cooling

Payne Heater I have a Payne gas heater that is about 15 years old. The flame will not start, but the blower runs constantly. Is it the igniter? I took a look at it and it looks to be in good shape, but when i turn the heater on, I do not see a spark from it.

    the blower turns on. Then hsi turns on and ignites the propane. Then the combustion motor starts and runs for 30 seconds. then the burner shuts down.

Payne 383KAV heater. Gas valve won't open to fire heater.


Being as how you changed the gas valve, make sure the arrow on the bottom of the gas valve is pointed towards the burner. Check for 24 volts at the common and main valve terminals on the gas valve when the thermostat is calling for heat...terminals MV and C. You will only have 24v there if the flame sensor senses flame... either pilot flame or main gas. You coud have 24v there without gas flowing or flame if is is a thermocouple standing pilot system and the gas valve is not in the 'on' position. But standing pilot systems usually do not have flame sensors.

With a flame sensor in the system, you have to have either spark ignition or glow coil ignition. If its spark ignition check for 24 volts at the pilot valve and common terminals on the gas valve WHILE the ignitor is sparking. That would be PV and C. The ignitor should spark and 24v should be on PV and C for 30 seconds to a full minute without ignition if it is a spark-to-pilot system.

If you have a glow coil, it will energize and burn bright orange for a minimum of 30 seconds BEFORE the main valve is energized. Then MV and C is only receiving 24v for approximately 5 to 6 seconds. This gives the flame sensor the time to prove the flame....if it does not prove flame, the system shuts down.

We have a 10 year old Rheem PVW50 Power Vented water heater that works on gas. The last couple of days it has been giving out problems. It will not maintain hot water in the tank. I restarted it and...


The igniter is glowing, but no gas ignites?
So either the gas is entering combustion chamber and not lighting because igniter is positioned incorrectly -or- no gas is entering combustion chamber because air in gas line or bad gas control valve thermostat or gas line is clogged.
When you 'restart' the water heater, somehow you are getting gas to the burner and it is igniting.
I'm not sure what the flame switch is. If the ECO was cut out, the gas control valve would not send power to the igniter and there would be no gas available for 'restart.'
I would adjust location of igniter, check if gas is entering combustion chamber, clean the gas line to the burner, and bleed gas line for air, but another suspect could be the gas control valve thermostat.
Identifying numbers are usually on side of gas valve.

Hello
Sounds like the flame sensor is bad.Or possible photo eye.Worst case would be a new circut board.

Anywhere from $100.00 to $300.00 depending.

Legally a home you purchase has to have a heater that works and a hot water heater that works,unless you made a deal with the seller.Or in this case the bank.I would question them on this issue.

Bradford White hot water heater - burner lights only 30 seconds


The slightly warm water makes me think of a thermostat problem. The fact that the heater is 10 years old I wonder how hard your water is. Calcium build up kills water heaters. But the yellow flame you mention could be the results of dirty orfices. May want to have a Pro look at that.

The whole assembly must be replaced.

The sequence of operation is -

Combustion fan purges the heat exchanger. A pressure switch verifies combustion air fan is running. Usually a 30-45 second purge before the hot surface ignitor glows, or the spark ignition starts.

Gas valve opens after 10-15 seconds and main burners light. Control board monitors for flame and shuts gas valve after 2-3 seconds if main burner does not light.

If burner does not light, some boards repeat this for 3 tries, then locks out and is reset by cycling power.

Air blower comes on after another 30-45 seconds after main burner ignition.

Times may vary based on the specific controller board. A flow chart and timing sequence should be located somewhere on the unit, usually in the fan compartment.

Heater will not kick on....buzzing sound. Took


You will find an error code chart on the wiring diagram pasted to the reverse side of one of the panels. It will help you to know where to start looking for the issue. I am also sending you the sequence of operation to give you a few more pointers, read on.

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).

The flame sensor is not sensing flame and the unit shuts off on safety. You can try cleaning the sensor, but will likely have to replace it. Also clean the burners. Sometimes there can be rust, dirt, or other dibri that causes an improper flame pattern and prevents the sensor from being fully in the flame.

With some units, the flame sensor is a seperate part, with others it is a part of the ignition assembly. Those can typically run 30 to 80 dollars for the part.
