Thermostat does not reach programmed temperature

Have you checked with a thermometer to see if the area is reaching the temp you have it set at? A thermostat has nothing to do with the temp in your house. If you have it set at a temp for Example ( 72 ) and it is not reaching that temp to shut off then you have a problem with your unit or insulation in house. If you set stat on cool at 72 and the house gets down lower than 72 then there is a problem with stat.

Unless you hit "hold" it will always default to the saved program settings after so long.

Can a Honeywell CT87N switch from Heat to Cool on its own? Twice now I noticed it was cooler in my apartment and I went to thermostat and it had been switched from Heat to Cool on its own...

That's very unlikely. I'd sooner believe the cat has been playing with it or it gets changed when someone wearing a backpack brushes past it (sometimes the straps or zipper pulls snag the oddest things). You can get a thermostat guard to prevent this if your landlord permits it.

I need to change Trane Weathertron Baystat 239 Thermostat over to Honeywell RTH6360D 5-2 Day Programmable Thermostat?

Question edited for clarity. Installation manual, but it has some very specific requirements. You may not have the correct one. The RTH6360 thermostat does not support L/A, S, or U terminals. If there are wires in terminals that are not listed, you will need additional wiring support. Visit yourhome.honeywell.com/support to find out if the thermostat will work for you. I don't understand that, and if you don't, you need a heating or electrical engineer.

Replacing a 2-pole baseboard heating thermostat

Here at home where I reside we have an old school thermostat that has the mercury bulb that acts like a sensor, and in other cases it could just be as easy as replacing the batteries in the unit itself, usually a lid that hides them, sometimes it works

My Honeywell oil-filled heater will not stop heating at the chosen temperature, but rather goes all the way up to 80 every time.

Probably a faulty thermostat. Time for a qualified engineer to take a look or to replace it.
