Customer Question

On June 7, 2013 we had a Trane 4ycy4036 XL14C installed. This is my problem, if I turn the thermostat to 68, the unit will stop heating at 65 or 66 degrees. In order to continue heating to 68, I have to turn the unit off and wait a 30 seconds or so and then turn it back on. We had the company that installed it come out and he replaced the Oem pressure switch. That did not solve the problem. Any ideas?
Thank you very much,

Thanks for your business!

Next time it quits heating before setpoint, go up to the unit, check the board for an LED flash code. Count the number of flashes before a pause and let me know what the code is.

The unit is on the roof and it's raining so I will not be able to check that unfortunately.

OK, well that's OK, question will remain open. Once I know the code, it will tell me what's going on with the unit.
