Byron for Model Number LRA257ST2 The other night I noticed my LRA257ST2 beeped and stopped running, and I got up to see what the deal was. It was on "econ", and I always run it on "cool". I pressed the button to switch it from econ to cool and it did nothing and made no beeps. A little while later it beeped again as if it reset on it's own, and I noticed the temp display was all black, not displaying anything in that square but the A/C was still running in econ mode (no idea what temp). The temp display has since come back but is nowhere near accurate..showing 71F and I've never had it below 76F.
