Hi
my parents have a newer model Coleman furnace. when they turn the thermostat on heat- cold air blows. the gas and elect gentleman said the pressure switch was not closing properly; we replaced it. furnace still comes on blows cold air and switches itself off..... any ideas?

Hi,

I am going to move this post to the HVAC forums, (Heating, Venting & AC.)

Please read the posting instructions in that forum and include the info in your post. The tech will be able to answer you much sooner.

Thanks,

Yep, we need to know the model number of the furnace and a more step by step sequence of how your furnace is acting.
