    Hi! emmamama
    Sorry there seems to be some confusion as the Boiler question (is used in water heating system for domestic hot water and heating) is in the Air Conditioner section. Most domestic boilers have an electronic control on the fire ignition circuit. If the sensor does not see a flame the control goes into lock out so a potential fire box explosion does not occur. This is used on all gas and fuel oil (kerisine) boilers. I highly recommend you have a licensed highly qualified boiler technician trouble shoot this system. This system needs to be inspected annually. Most fuel companies will have there technician check this for free, but a qualified factory trained technician is highly recommended. The only basic things to check are fuel system is on and a fuel oil filter needs to be replaced annually. Good luck and remember safety is first.

Explain your set up in more detail and that will give us something to go on, the answers above are both correct, but without some detail, all you can expect are generic answers, there is no way they could give you an exact answer. Nor can I.

You could be tripping out on overload electrical, created by answer one, or low voltage, or low or high pressure switches, a motor might be hanging and not coming to speed quickly enough, so many things, so more detail and we will get you fixed up.

Every air conditioner has a motor called a compressor. The compressor provides the cooling capacity for the air conditioner. If the compressor or its electrical controls are defective the compressor may try to start, fail, and create an electrical overload. If the unit does create an overload, every compressor circuit is also equipped with an overload safety switch. The safety switch is designed to protect the compressor from burning out. The safety switch will cut the power to the compressor for a certain length of time and then reset itself. When it resets it will allow the electricity to flow to the compressor once again. If the compressor then starts, the unit should function normally. If the compressor doesn't start when the overload resets, the overload will again cut the electricity to the compressor. This cycle will continue indefinitely. (Always allow three to five minutes before restarting the compressor.) If this situation is occurring, unplug the air conditioner and get help from a qualified repair technician. This problem is often fatal to the air conditioner because the cost of repair often exceeds the price of a new air conditioner.

When you turn on hot water tap the boiler fires up hot water for a few seconds the water becomes cold the boiler flame goes out then fires up again. when the heating on the flames stays on then off then on...


To avoid having a flame in the absence of water flow, the device you mentioned, 'diaphragm,' detects if adequate water is flowing to avoid a dangerous condition. Check on the housing of it for an adjustment screw; it may have a dot of sealant on it since these normally can be adjusted. It sounds as if it is misjudging the quantity of water flowing through and causing the annoying cycling.

Hi Jurgie,
I'm Harvey, the Master Plumber,
Happy to render my assistance.

This is your problem!
When you are switching on the boiler it ignites for 8 to 10 seconds, then it cuts off and the lock out lamp comes on. Pressing the reset button or turning on the hot water tap has the same effect.

I need to get the make and model of your specific boiler to give you an accurate answer!
Waiting for your response.
Harvey, your Master Plumber.
