    Limit switches work great for my Lennox Furnace

    Posted by John Lacey on 1st Feb 2019 6:11

    I ordered two limit switches for my furnace and replaced them a week after I replaced the original flame sensor assembly. My furnace recycling times have greatly improved and works more efficiently.The limit switches were easy to find here as soon as i put in my furnace model. So now I have a new combustion motor, blower motor, flame sensor assy, and limit switches. This 20 year old furnace is still going strong !!
