When troubleshooting Modine Hot Dawg, make sure the heater turns on, as this determines the type of damage from which the heater is suffering. If it turns on but runs poorly, there is an internal mechanism error that needs checking. If the system does not turn on in the first place, there may be extensive damage to the engines or some type of connectivity problem with the power source.Continue Reading
Before troubleshooting, inspect the warranty on the heater to see if it covers parts or labor. A warranty that covers labor allows professional servicing, but if the problem is relatively minor and the warranty is still in effect for the parts, you may want to just purchase the necessary replacement parts and repair the system as needed.
If it is possible to turn on the heater, inspect the thermostat and electrical section to make sure they are wired correctly. Sometimes poor wiring in the system results in long-term damage or operational errors. Sometimes, a calibration issue may result in the thermostat malfunctioning or displaying temperature readings incorrectly.
At other times, the issue is with the gas pressure if the fans are spinning and the igniter is clicking. Line pressure settings vary based on the fuel used for the system.Learn more about Appliances
