Three Flash Fault Code on Propex Heater
Mar 25th 2022
The Propex heaters were designed to be safe and reliable sources of heat for your vehicle. Being mounted in a non-stationary vehicle presents it's own challenges as the units are subject to vibration and exposure to all types of environments. Because of this, Propex designers err on the side of caution and create distinct operating parameters for the heating units. If the heater's electronic protection system senses that the unit is outside

Occasionally we receive inquiries into the Propex technical support team describing electrical conditions that are outside the typical diagnostic flow of the heater. This could be something like a heater working on the fan setting but not on the heat setting or perhaps having no response at all despite 12V applied and the onboard fuse testing good.It's important to remember that there are several opportunities throughout the course of heater ins
