Hi. My remote control Gazco fire suddenly won't respond to remote. The MAN and aerial symbols no longer show. The remote beeps now every 10 seconds. Batteries swapped with no effect. The green light flashes every second when cradled which I believe means it is still paired.. tried re- pairing but control box light wouldn't flash which maybe reinforces that assumption. Fire lights from control box. Control box batteries were changed a few weeks ago. Any ideas?
