I have a Vaillant GA92-100. It likes to turn on and off all the time, it heats the house and runs fine sometimes, but when it starts to turn itself on and off it does it up to 10-15 times in one minute.
So far I've done about everything I can think of and I am going crazy because I keep spending money and no results (Granted I have spent less than having a pro come trouble shoot)
I've replaced:
S8610u Ignition Control
The flame ignitor assembly (built in flame detector)
New Aquastat box
New thermostat (mainly because I just wanted a new one)
Checked most of all the wiring cant think of any other wiring to check.
I checked voltage on the gas valve that seemed normal
I jumped the t-tv to cancel out any bad thermostat wiring.
All to no avail, Its a long shot but maybe someone here might have a idea?
Here is a video of it doing what it does:
Thanks in advance.
