Fan blowing constantly

[Cedg97]

The thermostat will not stop blowing. Always running. Chatted with support and had me contact on-site tech for diagnostic. Don’t want to pay for diagnostic until I can determine if I need to replace unit. Only 2 year old and been working fine until now. 
suggestions please

Hello Cedg97,

I'm sorry for the trouble this may have caused you — let's see what's going on.

Do you mind me asking for the Case ID number from the support you chatted with? So that I can check and filter additional troubleshooting steps for you.

I'll look forward to your response.

Best regards,

Mark
