I have a Lennox system
XP14-036-230-10 CBX32MV-048-230-6-07
Installed 4yrs ago prior to my purchasing and moving into a 1600 sq. ft. ho me (town home mind you-inside unit).
Last Wednesday my indoor temp was not moving off 66 degrees and indicated A UX heat. Mind you I just put my heat on for the first time maybe a week or two prior and honestly have no idea if it ever even worked b/c it wasn't th at cold, but I think it was working....
I checked the breaker, nothing would make the outside fan kick on but when I changed the setting on the thermostat it would click like it wanted to wo rk but nothing happened.
I was told that both TXVs needed to be replaced. Once my guy finished the j ob and was exiting he noticed there was no air coming out of the systems, h e checked and the computer, module and fan had both gone. He replaced them all along with the outside fan. My inside unit is 4tons (meant for 2400 sq. ft.) and my outside unit 3 tons. The inside unit is too big and forcing th e air out so fast that it "doesn't have time to heat up." Well that's all w ell and fine but the system was working just fine for 4years. I understand the inside unit may be putting stress on the outside unit and vice versa he nce why the parts may have gone bad so fast but I paid over a $1000 and my system is not fixed. Also the power strip that was installed for the inside unit is smaller than what is required causing again a strain on the inside unit. Not only am I pissed because who gets paid to NOT fix something but the only thing working again is the blower. Blowing COLD air (66 max) and m y AUX heat is stuck on! I have turned the system off.
I am looking for answers/suggestions? Other than replace the entire system for almost $6k!
