Why are my clothes not drying in my Primus D13 Dryer?

  Christopher MillerAug 16, 2025
  If clothes are not drying in your Primus Dryer, several factors could be at play. First, ensure you've allocated enough heating time for the load. If the burner isn't igniting or is going out repeatedly, consult the corresponding sections in the manual. Also, too much water in the clothes before drying, an overloaded machine, a blocked exhaust duct, or a clogged lint screen can prevent proper drying. Make sure that the drying selector is properly set and that the voltage is correct. An inoperative thermistor or exhaust damper binding can also be culprits. Ensure adequate make-up air and that the exhaust system is not blocked.

  Robert JacksonAug 22, 2025
  If your Primus Dryer's tumbler is overheating, several factors could be responsible. Ensure that the main burner orifices are correct and that the gas pressure is properly adjusted as specified on the serial plate. Lint buildup in the lint compartment or ductwork can also cause overheating. Additionally, a restricted or inadequate exhaust system, an inoperative thermistor, or a binding exhaust damper might be the cause. Make sure that there is adequate make-up air.

  Angela CampbellAug 26, 2025
  If the burner in your Primus Dryer ignites and then goes out repeatedly, check the gas supply and pressure to ensure they are sufficient. An inoperative cabinet or stove thermostat could also be the cause. Other potential issues include improper orifices, an inadequate exhaust system, excessive igniter to burner clearance, inadequate make-up air, or broken, loose, or incorrect wiring.

Why does the motor overload protector cycle repeatedly in my Primus D13?

  Dana FisherAug 28, 2025
  If the motor overload protector cycles repeatedly in your Primus Dryer, it could be due to several reasons. Check if the voltage is correct and ensure that the clothes load isn't too large. A binding cylinder, inadequate wiring, or insufficient make-up air can also cause this issue. Additionally, lint buildup around the tumbler, poor maintenance, or broken, loose, or incorrect wiring may be the cause. Clean lint accumulation on and around the motors and refer to the wiring diagram.

  Nichole HughesAug 31, 2025
  If the burners in your Primus Dryer are not burning properly, it could be due to dirt in the burner. Remove the burner and blow out any dirt. Also, check the gas pressure against the serial plate on the back of the tumbler. Ensure the orifices are correct for the type of gas specified on the serial plate. A restricted or blocked exhaust duct or inadequate make-up air can also cause this issue. Disassemble and clean the exhaust system.

Why does the loading door open during operation of my Primus D13 Dryer?
- C
  Carol GutierrezSep 6, 2025
  If the loading door of your Primus Dryer opens during operation, it could be due to the tumbler not being properly leveled. Also, an excessive load in the tumbler might cause the door to open. Remove part of the load and restart the tumbler. Finally, the loading door strike adjustment may be incorrect.

  If the burner in your Primus Dryer does not ignite, several issues could be the cause. Check if the drying selector is in the “Cool Down” or “No Heat” position and select a heat setting. Ensure that the gas shut-off valve is open and that there is an adequate gas supply. Lint buildup in the lint compartment, damper, or ductwork can also prevent ignition. Other potential causes include an inoperative airflow switch, cabinet thermostat, IEI control, motor switch, microprocessor, accumulator switch, or C1 relay. Also, broken, loose, or incorrect wiring, improper igniter to burner tab clearances, incorrect orifices, an inadequate exhaust system, or the IEI control being in safety lockout could be the reason. For European models, try resetting the IEI by pressing the reset button on the back of...
