I live in Florida and the possible ice warning was displayed and the outside temp read 5 degrees. after a few min the temp went up to the 89 degrees. after a few min it dropped to 60 then back to 83.Is there a sencer acting up. A few weeks ago the battery went dead dead. I put in a new one and little things have been happening like tis. Is it major or a miner repair. -
