Product details
The Raypak H000334 is the coil temp sensor, the genuine Raypak replacement temperature sensor for the coil.
What it does
The sensor reports coil temperature back to the heater control. The control uses that reading to decide what to do next, so an inaccurate sensor produces decisions made on a temperature that does not exist. That commonly presents as a fault code or a heater that will not fire, even though the burner or compressor side is in good order.
Before you order
Raypak fits more than one temperature sensor across its heater and heat pump range, and they are not interchangeable. Check the part number called out for your model against H000334 rather than going by appearance.
