  If the primary heater temperature drops excessively while spraying with PMC Industrial Equipment, it could be due to several reasons. The chemical in the containers might be too cold, or you might be exceeding the flow rate specification of the machine. Another potential cause is that one or more of the fire rods in the heater have malfunctioned. To check this, remove the heater cover and disconnect the wires to measure the resistance across each rod.

  If the primary heater isn't heating and the controller displays ambient temperature on your PMC Industrial Equipment, start by checking if the light on the on/off switch is lit. If not, replace the switch. Also, check the heater breaker in the main console and reset it. If it trips again, use an Amp Clamp to check the amperage. If it doesn't exceed the breaker's rating, replace the breaker. If it exceeds the rating, one or more fire rods are likely shorted. Next, open the console and find the solid state relays for the heaters. With the heater on, check if the LED light is lit on the relay. Use a DC volt meter to check the voltage across positions A1 and A2 on the solid state relay (smaller wires); it should read 4-6 volts DC. Also, check the AC voltage across L1 and L2 (heavy wires), whic...
