Why does my furnace cycle on so frequently? 4x in last half hourPost created: 2012-11-14 Type of Equipment: Furnace Views: 17Just had service done, was told ventor motor was noisy, would need replacing eventually. Since then the furnace seems to be cycling on frequently, 4x in the last half hour. (Lennox G61MP, installed 2005) Are the service and the problem connected? How urgent would this appear to be?
