Opensprinkler v1.4u.

The PTC fuse next to the power switch gets very hot. A station will run for about 10 to 15 minutes then the unit faults, usually with the LCD dimmed. Unplugging then powering returns the unit to previous operation.

Power Supply output- 24VAC, 750mA
VIN-GND 5V, Over range Ohms
VCC-GND 3.3V, Over range Ohms
Can cycle through stations- ~25V output, 0.18A on the active station.
Rainbird Valve #35006905

Seems like this load shouldn’t be a problem based on the previous posts. What should I check to trouble shoot?
