Check all the gas jets on your heater unit. Spiders love to buld little webs in these things and it might prevent gas from reaching the ignitor.

This sounds very much like spider webs in the gas orfaces. If you shut the power off and remove the wires to the gas valve then shut the gas down and remove the fed pipe from the gas valve you should be able to pull the burner tray out of the heater. Now if you remove the burners you should be able to remove the brass orfaces connected to the main gas feed pipe. If you use an air hose or a can of compressed air you can blow this out now. Now take the orfaces you removed and clean them with a tooth pick or a small piece of wire. The webs will look like small cotton balls or lint. They don't stop the gas they just slow it or disperse it and keep it from firing clean and evenly.
At this point you can reassemble the tray and install. This should fix your problem.

Your bypass valve is bad. Probably because you did not pay attention to your water chemistry. It is located where the pipes enter the heater. You remove it from the side of the manifold that is outside the heater. It is not a difficult job. Just make sure your pump does not come on while the heater manifold is open!

What is a 1F code on the hayward pool heater


The code you are referring to is actually IF, not 1F. It stands for ignition failure.
If the control exceeds the maximum number of ignition retries or recycles the heater will shut down and go into lockout. Automatic reset is 60 minutes.

My heater/blower fan will not shut off in my 2005 envoy even after my ignition is turned off and key is out, i've read a few similar problems on this, what is the solution and how much will it cos


Depending which HVAC system you have Manual (sliders for temperature) or Auto (digital readout), the control module is likely at fault. The Manual HVAC has a Resistor Module (which have a high failure rate) and the Auto HVAC uses an electronic module. Both of these are mounted next to the blower motor located behind the glovebox.

I have a 150,000 BTU NATURAL GAS HEATER. IT WILL RUN FOR 10 SECONDS AND QUITS. IT WILL NOT IGNITE AGAIN UNLESS YOU SHUT IT OFF AND RESTART


Hi,
The heater is not proving the flame...and shutting down on safety...
Check the flame sensor and all connections of the ground from the burner to the ignition control...
The control may also be bad...
for additional help with Dayton units go to www.grainger.com
they sell that brand and have their own repair help techs.

Pool heater gas fire lights up and turns off 10 secs later


Assuming you don't hear any banging noises, that cycle is by design. There is a fault. 2 possible causes are the ignition board is bad, or the ignition sensor is not returning a voltage indicating the flame is lit. Take this out and put the ignition piece on your stove flame. Check for voltage while on flame (DC millivolt setting on multimeter). Put one probe on ground other on sensor lead. If it doesnt have voltage this is bad. If you do, its possible your board is bad.

Rinnai burner goes out when ignition button is released


The thermocouple [s] require replacement, or in my experience try servicing the unit first. There is an injector for the main pilot and a secondary injector for the flame thrower ignition. Both of these are prone to blocking due to dust and can be enough to shut the unit down. Although usually this is thermocouple related as you are manually keeping the unit running when you hold down the button, if the tcouple is broken it wont send enough millivolts to hold the magnetic valve open when you release the button.

Furnace shut off after 3 time flame from pilot


Sounds like you may have a weak or bad flame sensor. If the circuit board does not sense a good flame it will not light the burners. Also if your furnace is 5 yrs or newer it should give you a fault on circuit board in the form of a blinking or a code itself.
