The Applied Comfort PTAC Parts Most Often Replaced
Applied Comfort PTACs share many parts across series, which keeps service simpler. Air Distributors is an authorized Applied Comfort distributor and a designated Preferred Supplier, and these are the parts we ship most often.
Main control board: 801843
Used on all Applied Comfort PTAC units except those with power dampers. It controls heating, cooling, and the fan.
Symptoms: the unit powers on but ignores the controls, or cycles erratically.
Touchpad membrane: 801834
The control interface for all Applied Comfort PTACs. Membranes wear from use and cleaning chemicals.
Symptoms: some buttons work and others do not, or the display behaves oddly. A failed membrane is cheaper than a control board, so check it first.
Condenser fan blade: 803577
Common to several models, including the K, SC, and 16 Series.
Symptoms: noise, vibration, or high-pressure trips. Blades are often damaged when a chassis is pulled or by debris. Replacements must match diameter, pitch, and rotation.
Heating element: 124099
Used in DM and EA units, rated 3.4 kW at 230V.
Symptoms: the fan runs but there is no heat, or the unit trips its circuit in heat mode. Match the wattage and voltage of the original.
Other parts we supply
- Fan motors and blower wheels. A unit that heats or cools at the coil but moves no air usually has a motor problem.
- Filters, the most frequent maintenance item
- Sensors, thermistors, capacitors, and contactors
We stock parts for current and legacy series, including the 16, CM, DMQ, EA, J, JK, K, NA, NF, NY, RS, and SC.
