I have a freestanding gas stove by Heat&Glo, it's the Paloma model with the Intellifire ignition system. It's controlled by a wall mounted thermostat.
1) the pilot light stays lit at all times instead of being intermittent. If I shut off the gas, unplug the unit, then restore power and gas...there is no pilot. But once I turn the unit on, the pilot is on for good.
2) with thermostat set below room temp and set to "off", flame pulses across the manifold with a 2-3 second delay between pulses. Almost like the unit is being turned on/off in rapid succession.
Everything worked great for the first two years of service. I recently had the dealer come out to service based on these symptoms. They replaced the Control Module DSI (whatever that means) but the problem persists.
Is there an obvious cause? I'll be calling the dealer back out for service, but would like to have some background info before doing so.
Any help would be greatly appreciated.
