We have a small Danby Fridge wth freezer in our cabin. It has a CO alarm attached. We cannot get it to light using the push ignighter, but we can remove the box and light it manually and it stays on no problems. I recently cleaned it and it worked fine before then. Any thoughts on how we can get the ignighter to work? It is a propane fridge and the batteries in the CO alarm work...it stays on when we light it manually
