We have a miller trailer furnace and it was running weird, so I did the simple stuff like changing the filters , changing the nozzle . Now it just will not fire . Could the eye be bad and not letting it fire or is it the transformer? It was replaced in 05 for like the 3rd time .our land lord has put us off because he said we have a wood furnace but its not enough to keep our house warm , we have a little one in the house and it gets pretty cold in here like 62. Please any quick help would be greatfull. Thanks Paul
