Rinnai Replacement HD50i VR Series Sub PCB/Surge Protector (P50IVR-701)
Most attention when troubleshooting a Rinnai HD50i naturally goes to the main PCB, and for good reason — most faults do trace back there. But the sub PCB is doing an important job in the background, and when it fails, the symptoms can be easy to misread.
This component combines a sub PCB and surge protector in one, managing the electrical link to the solenoid valves via a secondary circuit board, and protecting the appliance's main electronics from voltage spikes coming in on the mains supply, whether from the grid or nearby lightning activity. This genuine Rinnai part, made to the original specification for the HD50i (VR2632FFUDHD-E), restores both functions where the original component has failed or been damaged.
⚠ Important: Installation and servicing must be carried out by a qualified technician familiar with Rinnai products. Turn off the gas supply and disconnect power before beginning any servicing.
Key Features & Benefits
Perfect Compatibility: Genuine Rinnai component for a seamless fit with the HD50i.
Dual-Function Component: Addresses solenoid circuit integrity and surge protection in one part.
Protects the Main PCB from Power Surges: First line of defence against mains voltage spikes.
Quality Assurance: Manufactured under Rinnai's own quality controls for reliability and longevity.
Safety First: Replacing a damaged sub PCB with genuine parts reduces the risk of further electrical faults.
Ideal For
Rinnai HD50i water heaters (VR2632FFUDHD-E).
Sub PCB failure diagnosis and repair.
Surge damage repair following a mains voltage spike.
Qualified technicians familiar with Rinnai products.
Common Problems This Part Will Fix
Solenoid Valves Not Working in Fault Conditions: Restores solenoid function linked to the sub PCB.
Main PCB Damaged by a Power Surge: Replaces a sub PCB that's failed to suppress a mains voltage spike.
Visible Burning or Damage on the Sub PCB: Replaces a component confirmed faulty on inspection.
Electrical Faults Persisting After Main PCB Replacement: Addresses the sub PCB as the actual root cause.
Why Buy This Product?
This component sits between the mains supply and your solenoid circuit, quietly absorbing surge damage before it reaches the main PCB. Fitting the genuine part restores both functions in a single component, rather than leaving the appliance's electronics exposed to whatever the mains supply sends next.
