Restore reliable cold water in minutes
- Fixes “no‑cool” or “over‑freezing” symptoms by replacing the cold control (thermostat) that regulates the H2O‑PRO’s refrigeration cycle.
- Made for the H2O‑PRO platform sold by Pure n Natural; pairs with existing leak‑protection and hot‑water safety features described in the owner’s manual.
- Quick swap, pro‑friendly: standard spade leads and capillary‑bulb sensing design for fast service.
Best for: offices, clinics, and breakrooms where the H2O‑PRO has stopped chilling or cycles erratically (too cold/ice‑up). A fresh thermostat is the typical remedy on water coolers showing these symptoms.
In the box & installation
- Included: H2O‑PRO cold thermostat (replacement control)
- Install (summary): Unplug cooler → shut off water → remove top/front panel → note lead orientation → swap thermostat & sensing bulb → reassemble → restore water/power and test for stable cooling. (Typical water‑cooler repair steps; see your service tech for model specifics.)
FAQs
How do I know the thermostat is bad?
Common signs are no cold water or a frozen cold‑tank. On water coolers, the cold control/relay are usual suspects; replacing the thermostat often resolves it.
Is this the same as the “hot” thermostat?
No, this listing is for the cold control. The H2O‑PRO manual discusses hot‑water reset/safety, which is a separate function.
Will this fit other H2O models (H2O‑850, 2200, 2250, 2500)?
This listing is for H2O‑PRO. For other International H2O models, see their product pages/parts or contact us to confirm.
