Trouble with my Trane control board CNT#3797
Hi,
I just replace my Trane control board CNT#3797, with a White Rodgers CNT#03797. Now, I am getting 3 flashing safety lights. I had the Unit service a month ago.. I was told I needed to change the filter.. I didn't know this until 3 weeks later after I got the invoice in the mail (its a rental unit). Could this have cause any blockage or maybe wrong wiring on the new control board? I have already spent some much money and time on this... Its getting really frustrating.. the bad part is I called a professional and he can't figure out what wrong.. and I have already spent over $600. In expense... Please! Please help!! |
