Troubleshooting a Raypak Digital Pool Heater

By John Albers

Excess soot caused by a Raypak digital pool heater can be caused by a number of things. First check the burner intake ports. Insects, dust, or other debris may be clogging the ports and causing the gas to burn inefficiently, resulting in soot. The burners themselves might be dirty. If it's been more than five years since they were last cleaned, they should be cleaned again. Finally it's possible that the Unitherm Governor may not be functioning properly. This device causes the burners to shut off once the pool water has gone above a certain temperature; default setting is at 110 degrees Fahrenheit. Pour water over the Governor that's well over 110 degrees. If the burners don't shut off, the Unitherm Governor needs to be replaced.

Raypak Digital Pool Heater Turns On and Off Continuously

Typically a Raypak digital pool heater will click on and off when it's not receiving a continuous flow of water with which to get a steady reading of the pool's temperature. Clean out the pool filter and put more water in the pool to make sure the pool skimmer is receiving a strong steady flow of water. If this doesn't help, then the external bypass valve on the pool pump may be engaged, preventing water from reaching the heater. Adjust the valve.

Raypak Digital Pool Heater is Making Noise

Noise is most often caused by an obstruction or debris inhibiting the flow of water or gas through the heater. Begin by performing a manual flush of the system as described in the Raypak digital pool heater owner's manual. This will vary depending on the exact model type. Check the gas line. Turn off the gas flow, disconnect the lines, and blow air through the lines until any debris or obstruction has been pushed out. Should this fail to stop the noise, scale from hard water may have built up within the heat exchanger. The heat exchanger will have to be scoured clean. This should fix the problem.
