Nice gates don’t close after the ambient temp is high

[Howard]

Good afternoon 
I have a set of Nice gates with a Nice controller (unsure of model number as no literature) approx 18 years old. If the ambient temperature is belowv19/20 Celsius the gates open and close fine. If the temperature increases then the gates open but won’t close until the temperature drops below approx 17/18 Celsius. Has anybody got any thoughts
Many thanks

All gate equipment has problems, old nice boards suffer from frozen eproms. Gates ease of movement can change over time, so a relearn may be neccessary, unfortunately the board may be locked due to the corrupted eprom chip.
18 years is way past the designed life of Nice equipment, boards suffer from failed/scorched relays, blown capacitors, dry solder joints etc...
Sounds like it requires at the minimum a new board, if 230v motors go with a Beninca brainy 230v board, we've never had a problem with these as a replacement and they're cheaper than BFT. Don't touch the FAAC e145S it still has bugs and requires Simply connect pro to install correctly.
