Hello, thanks for using this service I will be assisting you today. When you respond to me sometimes it may take me a bit to respond back as I am researching your issue and it takes time to type so please be patient.

When you say it crashed what has happened exactly?

can you call my cell xxxxxxxxxx

system was working till i played with the sensors and now no fan or cool. had a hf 41 failure.
Expert:  HVAC Guru replied 1 year ago.

Ok that is a ZONE 2 temp sensor error, the sensor is reading shorted or open. You need to check the sensor and the wiring to the sensor you may have knocked something loos or created a bad connection to the controller. Check that and hopefully the sensor is still fine it may just be a loose connection.
