The heat and pressure sensor is worn out! Be ready to perform the below type of work to fix the old one. Generally what occurs is the units soldered connections on the main power board warm up as the system warms up. Thus, the loose capacitors, resisters, and diodes are causing the CHANGE when the system warms up. When metal contracts, it expands thus losing the connection needed for a solid connection. This process is normal after the units have reached their service life. Keep in mind that you can repair this but at the expense of time if you have never performed this type of work.
