Lopi Berkshire stove -- spark, but no pilot or flame

[Jozxyqk]

Hi we're snowed in in the current Washington state blizzard and just lost our only heat source so hoping for some help! All the service places are backed up for days at least.

We have a Lopi Berkshire. It's been running a lot the last week or so, and is our only heat source.

This morning it stopped lighting. We replaced all the various batteries. If I remove the fake "logs" I can see that there is a spark to the pilot light, and we can hear the clicks, but other than that no action.

At our wits end, any help would be much appreciated.

Need more info. Are you on natural gas or propane?. Have you taken off the glass and do you smell gas when trying to light it? Is this a standing pilot stove or intermittent pilot stove (IPI)

Millbilly:

Thanks! I am natural gas. I've taken off the glass and removed the fake "logs" and grating. I'm going to try and attach some pics of the relevant innards.

There's no gas smell. The stove has a switch you can set to standing pilot or "green smart" where it turns off. We normally keep it on the setting where it turns off when not in use.

Your help is much appreciated.

Do you hear anything coming out of the pilot besides the clicking sound? Do you have a multimeter and know how to use it?

On a call for heat, what should happen is that the electronic control module turns on the gas for the pilot burner and the spark to light the pillot. When the pilot lights the module detects the lit pilot by flame rectification across the flame sensor, which should be engulfed by the pilot flame.

When the pilot flame is detected, the spark is turned off and the main burner gas is turned on, to be lit by the pilot burner.

So---- how far along in this process do you get? Does the spark continue to try to light the pilot burner? Is gas coming out of the pilot burner for the spark to light?

You can usually turn the electric gas valve to the pilot position, which allows gas to flow to the pilot burner when turned on by the module, but doesn't allow gas to go to the main burner.

So you can turn the gas valve to the pilot position and then inspect carefully what is happening with the pilot burner ignition process.

Describe what you are seeing, including a description of the appearance of the pilot burner flame if it is lighting.
