I was climbing out of 15;000 feet to FL230 when my TBM had a cabin decompression light come on. Everything else looked normal but I put on my mask and the told a lady controller I had a decompression light on and wanted to drop down and she asked if 11;000 would be ok and I said great and meant it. She was perfect. I then had to drop down to 10;000 to finish my trip. The next day another pilot and I took the plane to FL230 and everything checked out but I am going to take it the shop and have them check it out. I think it may have had a bad signal from one of the sensors which read false.
TBM pilot notices a cabin decompression light passing 15;000 feet and descends to 10;000 feet to complete the flight. The next day the aircraft is taken up to FL230 without any issues.
