Following your comments, i have opened the enclosure, disconnected the power supply and measured the fan current ( 40mA) when connected to AC line.
Ordered a 4020 model 12V with the proper current, seems very common My 53132A will be back on stage very soon Thanks for your help.

The supply apparently does need the fan cooling to keep it happy. Since the fan runs whenever the counter is plugged in, the fan logs a lot of hours. If you do loose the power supply, the one in the 53181 will swap over to the 132. It’s not a cheap fix, but better than scrapping a 132.
