???Fridge will not "spark" up on gas after pushing in the gas control knob and pressing the ignition button.It lights up sometimes but soon as you release the knob it goes out. I have replaced the thermo coupling and cleaned the jet and gas lines i think it can only be the electromagnet or as some one said the solinoide. Last year the service guy lit it time after time and it worked but fortnight later whilst away it stopped again.Appreciate any advice.
