Re: lock out light
These furnaces have a sequence of operation , 1 thermostats calls for heat,2 purge fan checks flue is open and not clogged ,3 checks to see if hot plate ignitor or spark ignitor is on 4opens gas valve 5 checks for flame and allows valve to stay open 6 checks for temperature rise and brings on fan , if any of the process is not there or interruptedtrys 3 times and defaults to lockout , that is the best answer with out knowing what type you have , hope i helped

See if big red knob has a PILOT or LIGHT setting and put it on that setting. Next look at knob on bottom-- it should have a circle cutout on it that needs to align with the pilot push button. The cutout lets the button be pushed in. While holding button in---light the pilot and keep holding the button in for about 3 minutes. If everything is working right with the water heater, after 3 minutes or so you can let go of the button and the pilot should remain on. If it stays on. turn the smaller button to the run or heat position and the big burner should come on. Then set the big heat control knob for the heat setting you want.
If when you turn power off you wait a while it is probably not the central system coming on. You have a triple aquastat that maintains a temperature level needed to provide hot water. but you are not getting the thermostat to operate the central heating. The thermostat is a switch that operates by temperature. if you have tried raising the thermostat and the system did nor kick in. try jumping the thermostat terminals in the aquastat . if that works then the problem is either in the thermostat or the wiring to the thermostat. also with a electrical tester." while the thermostat is jumped" test the c1 and c2 terminals to see if power is going to the circulator. If not then you need a new aquastat. if you have power and the pump is not moving water replace it.
can you look inside combustion chamber and see if fuel is being coming out of nozzle and if you have a spark across the electrodes?. How long has it been since it has been taken apart and cleaned ? Has the oil filter been changed? You probably need to have it cleaned if this has not been done over a year.
I assume the water heater and water inside it is cold (otherwise you would not be lighting it). You light the pilot. The main burner comes on and the pilot lights it. The main burner should stay on until the tank is hot, When the tank gets hot the main burner should shut off but the pilot stay on. If you draw hot water, cold water will run in and cool the tank. If yu do nothing the tank will eventually just cools off. then the main burner should come back on to reheat the tank.
What kind of water heater do you have? In any case, it sound like a plumber should check out system.
Do you have indirect heater that gets heat from central heating boiler? Most indirect/boiler combo heaters have control that is set to heat the water first. If water is not getting heated, then the control needs repair.
Do you have gas water heater with gas central heating? The central heater may be drawing so much gas from meter, that other gas appliances are unable to function. larger gas meter or gas line may be needed. Or if furnace and water heater vent on same chimney, the backflow from central heat could be affecting burner on water heater especially if water heater has electronic sensor that stop combustion if air quality is bad. Venting problems can lead to CO poisoning, and are a serious matter.
Hi - hope someone can help. I have a VOKERA EXCEL 80SP combi boiler and been without hot water/central heating for two days. The pilot light is on, the fan is on, but boiler not triggering once the hot water tap is turned on.
Hopefully someone come to look at it today but hoping for some advice. Anyone else had this problem?
your blower motor is trying to seize up on you, it is time to change it, if the fan doesn't come on first your water heater should not light, the fan comes on first to get eccess gasses out of the burner compartment,, do not light with ot the fan first it could combust
I have a Siemens "Radio" Room Stat - the receiver has switched itself off. How do I restart it. I have pressed the restart button and the reset - nothing happens except for red light flashing and then off. I do not have the instructions. Where might I get them?
