Help with Trane Model 2TWB3030A1000A
Have a Trane Model 2TWB3030A1000A. As we have had some hot days, cut it on for the first time. House was reading 80. After being outside for about an hour came in and temp was 82. Unit is blowing inside but only hot air. Checked the obvious, thermostat set at 76, it is on cool. Went outside and noticed that the fan is not blowing out there.
Found info about checking the fan to see if it was locked up. It will spin freely, and will sometimes start with help. Shut unit down and waited two hours and turned it back on. Unit started as well as outside fan, but after about 1 minute, outside fan stops.
Replaced capacitor as this was least expensive place to start. No change, fan will come on for about 1 minute then stops. Have checked wiring and all appear tight and no "charring" on any of the boards.
Any other suggestions prior to calling for service?
