Living room lights flash on when furnace starts

Thanks Max! I didn't experience any power drop and, alas, I have only a manual (not digital) thermostat so maybe I was spared the problem

Yup, if you change it to a digital, you will have the drop in the form of a thermostat reset. This is only trailer I have not just been able to swap an analog thermometer out with a battery powered version.

I have a 2018 26.5 RLDS 5th wheel. We usually use an electric heater to save gas. This past week the electric heater quit so we started using the furnace. Lights in the living room/Kitchen flashed every time that the furnace would ignite. My research came up that a noise filter is required in-line on the dimmer circuit. Called the closest Jayco dealer and they had the noise filter in stock. numbers on the part are AP-HRN-684 WO:142106 REV:A Will report back when I get it installed.
