responsible for establishing the pressure differential required to safely exhaust combustion byproducts through the flue vent pipe

which is essential for optimizing blower motor operation by allowing the coil to reach temperature before airflow initiates and purging residual heating or cooling after the cycle ends

this replacement diaphragm is compatible with Honeywell MP953A

effectively protecting the thermostatic expansion valve (TEV) and compressor from abrasive solids and varnish
