Question about GE 36 in. Profile JGP962 Gas Cooktop
My frameless touch control ceramic hob is flashing '7A' when it is switched on. There is a constant alarm beeping and the hob will not work
I have a Stoves 900 CTH with the same problem. Its been like it for about 6 months and we're still able to get it going eventually.
If you turn the power on at the mains and leave it beeping for about 2 hrs then press the power on touch button. You should see all the "0."s flashing. When the flashing and beeping goes slow try pressing one of the hob buttons alot until the little dot illuminates next to the 0 then quickly lit the + button.
It sometimes works after 5 mins but other times it takes 20-30mins and is a real pain in the ****.
I did ring Stoves a while back and they quoted me £190 for the pcb but I hardly use it so just lived with it as it is but I finally had enough tonight and done a web search which turned up this thread.
I've just pulled it to bits to see if I could locate this "C17" but not 100% sure what I'm looking for.
Is it the big silver thing in the center with 5B RVJ on it?

Hi, this worked for me as well on a 900CTH. Has to be a design fault judging by the number of people with the same problem.
No idea what this capacitor does but a guess would be that it is the reset circuit for the processor. This is normally a simple CR circuit which holds the reset pin down so the processor resets on power up. Only in this case their design does not hold the pin down long enough hence increasing the capacitor from 220 to 1000 micro-farads increases the time constant so that the pin is held down long enough. The installed value probably works well initially but due to the heat on the hob the capacitor ages, capacitance decreases in value (a common issue with electrolytics) and low temperatures at start up exhibit lower capacitances hence the fault is, as reported, worse in cold conditions. So my additional advice would be to pick a replacement with a high temperature rating.

I have fixed mine with a new pcb £189.00 not cheap.
