Customer Question

I had a new Lennox furnace installed this summer. I tried to turn the heat on for the very first time yesterday and an error code "207" or "270" came up on my thermostat (heat didn't turn on).

If the furnace did not fire it would be code 207.

If the furnace DID start but then later coded it would be 270.

Which is your situation?

I do not believe it ever fired

Thank you,

then you will want to call for warranty service as the hot surface ignitor is broken. chance it was 270 the unit overheated...which also will qualify for a warranty call unless the filter was plugged.

In either choice it would be prudent to call the installing contractor.
