My fridge won't light on gas ! The piezzo can be heard and the warning light flashes, it tries to light and will not actually ignite. Not used the gas side of the fridge for nearly a year. Please can somebody help.?
There is a thermocouple which sits in the flame of the burner which has to be hot to keep the solenoid valve open. Normally, when lighting a fridge, cooker or a gas fire, the on-off knob on the controls has to be held down for a few moments after the burner has lit itself. This is to allow the thermocouple to reach its operating temperature. It then generates a small voltage which is used to hold the solenoid valve open. This is a "fail safe" device so that, should the gas flame blow out, the gas is cut off until you physically relight it. There is a similar system on the cooker and gas fire. Are you holding the knob down for long enough?
Dust, spiders webs, general detritus. Could be that it just needs a jolly good clean.
In view of the fact that it tries to light but won't could mean that then gas is not getting through. How long did you give it before throwing in the towel? If the isolating tap has been closed then turned on again, it will take time for the air in the gas pipe to clear itself via the burner
