I will be happy to help.Tell me is going on with the thermostat
Issue may be that you only have a single speed motor or only one speed connected. Can you look and see if we have wires to each speed terminal?
Temp sensitivity should control heat only, cool only or both ,again depending on if you have both heat control and cool control wired or just one or the other.See below
If only a single speed fan wired all sounds good and same if you just have heat or cool.ou would need to verify wiring to know for sure.
I am in south Alabama so no idea of a reputable service company in LA.I would suggest Googling Chillers or HVAC contractors to find a reputable dealer.
I suspect thermostat is probably fine as it is rare for these things to go bad.
There are probably more modern stats available but again an onsite tech is best in making sure of compatability
I am going to attach a link o a manual so you can see exactly how the thermostat should work based on whether you have wired for heating,cooling or both
