no cooling - wrong thermostat?

My A/C blew air only a couple degrees colder than the return air. I disconnected the red wire from RH terminal by removing the jumper between RC and RH. A/C works fine now (temperature difference is about 15 degrees). So, I don't have heat now (it's OK for a next few months) but how can I fix this for good?

Welcome to the forums.

A little more information would be helpful. Make and model of heating system.
I'm guessing a heat pump with electric reheat coils.

So right now the red wire is just on RC and nothing on RH...... correct ?
It would almost suggest a thermostat problem.

In your post you ask if it's the " wrong thermostat" .... why.....was it recently replaced ?

It's Goodman AEPF air handler with single-stage cooling, heat pump and emergency heating.
Yes, red wire on RC and nothing on RH.
The thermostat White-Rodgers 1F95-1277 had to be replaced just after the installation about 4 years ago because of the same problem (according to the installer "cooling and heating was running at the same time").

sounds like the thermostat failed if removing the jumper fixed the problem..... You may want to replace it with something other that WR..... I would use a high end Honeywell. A high end Honeywell will at least have a 5 year warranty instead of a 3 year that the WR had.
