The frost sensing switch on a Rinnai HDC1500i or HDC1500e monitors ambient temperature and triggers the appliance's anti-frost protection when conditions drop low enough to risk internal components freezing. It's a key part of what allows an appliance to keep working reliably through cold weather rather than being caught out by the first hard frost.
This genuine Rinnai frost sensing switch is made to the original specification, restoring accurate frost detection where the existing switch has failed or is no longer triggering correctly. Fitting the genuine part keeps this protection working as designed through the colder months.
⚠ 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.
