Hello,
I'm having problems with my Rheem tankless RTG-95DVN as described below.
Connector labels per SVC 820P pocket manual pgs 14, 15
Initial state: branch circuit breaker tripped, unit inline 3a fuses both blown. Possibly associated with a power outage.
Whole house protected by industrial grade Innovative Technology Surge Protector, indicators unit is OK. Rheem was plugged into a garden variety, point of use surge suppressor which failed, as noted by tone alarm.
Action: replace 3a fuses, energize system.
Result: both fuses blow.
Action: replace 3a fuses, open all connectors on control board, energize system.
Result: red led on control board flashes 4 times and repeats.
Approach: with system deenergized, plug in 1 connector at a time, energize and note results
Action: connect U only, energize.
Result: 3a fuses remain intact, red led off not flashing.
Action: connect G only, energize.
Result: disc shaped component immediately to the right of G explodes, 3a fuses blow.
Is there a common problem that is associated with the circumstances noted, that you could point me toward?
How should i proceed to ensure that new control board is not damaged?
I have a Fluke multimeter for taking measurements.
Best Regards,
Tommy Hager
