Product details

The Hayward CHXTRF1930 is the genuine dual voltage transformer used in Hayward ComforZone CZ, HeatMaster HM2 and H-Series ED2 electronic pool heaters in the 150 to 400 model range.

What it does

Everything on the control side of the heater, the board, the display and the safety circuit, runs on low voltage that this transformer supplies. Line voltage comes in, control voltage goes out, and if the transformer fails the heater goes completely dark even though power is present at the terminal block. That symptom is easy to mistake for a dead control board, so put a meter on the transformer output before you replace anything more expensive.

Fitting

It is a direct replacement for the original transformer in the heater control box. Kill the power at the breaker before opening the panel, and note the wiring positions before pulling the old one out.

Questions and answers

What people ask about this product, answered by our pool techs.

Which heaters does this fit?
It is listed for Hayward ComforZone CZ, HeatMaster HM2 and H-Series ED2 electronic heaters, in the 150 to 400 model range.
What does dual voltage mean here?
The transformer is built to work on either of the supply voltages these heaters are wired for, so one part covers both installations.
My heater is completely dead. Is this the part?
It is a common cause. If there is line voltage into the heater but nothing on the control board or display, the transformer that feeds the low voltage side is a prime suspect. Confirm with a meter before ordering.
Is this a genuine Hayward part?
Yes. It is the Hayward OEM transformer, part number CHXTRF1930.
