Our take on the RAP38933 - Continuous Duty Motor Relay 12V (Master Relay)

This is the master 12V continuous-duty relay for HWH automatic leveling systems (610, 625 and 725 series). It takes power from the house batteries and passes it to the pump duty relay (RAP35723) when the ignition is switched to ACC or ON. It is a direct replacement for the obsolete AP7505, RAP7505, AP4276 and RAP4276 parts, so owners of older HWH-equipped coaches can restore the leveling system without rewiring. It suits DIY owners doing their own leveling-system repair rather than shoppers looking for a general-purpose relay.

Pros
  • Direct replacement for four obsolete part numbers
  • Continuous-duty rating suits the master relay's constant load
  • Specific to HWH leveling systems, so fit is known
  • Simple two-relay circuit: master feeds the pump duty relay
  • Installation instructions are published for the part
Cons
  • Only fits HWH 610/625/725 leveling systems
  • Not a general-purpose 12V relay for other uses
  • Correct operation depends on the coach being wired as HWH intended
  • Small sample of ratings, so long-term durability is unproven

What reviewers say

  • 4.9 / 513 ratings

Owners rate it highly and describe it as the right part for restoring HWH leveling systems that had stopped powering the pump. The main complaint is that it only suits HWH setups, so buyers with other systems have no use for it.

What people mention
  • FitPraisedOwners say it drops in as the correct master relay for HWH leveling systems.
  • ReliabilityPraisedBuyers report the leveling system works again after replacing the old relay.
  • CompatibilityMixedIt is praised for matching obsolete part numbers but is useless outside HWH 610/625/725 systems.

Questions and answers

Will this relay fix a leveling system that won't run the pump?
It can, if the master relay is the failed link. This relay feeds the pump duty relay (RAP35723) when the ignition is in ACC or ON, so check that relay too before replacing parts.
Which HWH systems does it fit?
HWH automatic leveling systems 610, 625 and 725. It is not a universal 12V relay.
Does it replace the old AP7505 or RAP4276?
Yes. It is listed as a replacement for AP7505, RAP7505, AP4276 and RAP4276.
Is it the same as the pump motor relay?
No. This is the master relay that sends battery power to the pump duty relay, RAP35723, which is a separate part.
Do I need to rewire anything to install it?
No rewiring is described. It works with the coach's existing HWH wiring, assuming that wiring is correct.
Is it continuous duty?
Yes. It is rated for continuous duty, which suits a master relay that stays energized while the ignition is on.
