Arrived on site customer stated that their unit shorted out. Upon inspection found that the connector the the circulator pump had shorted and latex the wire harness and circulator pump, also blew a fuse. Contacted tech support and they recommend replacement of those items listed above in addition to repiping the exhaust termination because it is done improperly and can be the cause of this issue and replacing the vent collar assembly because that appears to be leaking as well. Collected for tech support and collect $100 down deposit and will order in Navien parts and will contact homeowner when they are in hand and we can get them on the schedule.
