Mcb Posted December 6, 2020 Share Posted December 6, 2020 I turned on the furnace this morning and the AC came on instead. The furnace has been working fine up to this point ( as has the AC) so I was surprise. The thermostat scrolls through all the options in “mode”, shows the little heat icon properly, but when selected, the AC comes on. Checked the fuses, checked the gas, checked the owners manual where there isn’t much useful advice for this particular issue.. Anyone run into this before? Thanks!
