My Whitfield Optima 2 went through a power failure the other day. The stove was not "on" at the time (not operating, but green power light illuminated), but power was provided to the control panel before and after the lights went out. It is controlled by a wireless thermostat that was "off" at the the time. When power was restored, the control panel "clicked" several times, but would not start the stove. I turned the stove off and unplugged it from the power source. It started when I plugged it back in, turned the control panel on and turned the wireless thermostat to "on." However, the feed rate is constantly "high." I can control the fan speed at the the control panel, but I cannot adjust the auger feed rate. Do I need to replace the control panel or another element of the stove's controls?
