Hi Tammy,
Most likely the contacts are not closing all the time in the Air Pressure Switch due to becoming pitted.
Can't say for sure without testing it, but it is most likely by what you stated.
Pressure Switch # 024-27666-001.
If interested, go to below link and order it through PayPal or call toll free to 1-877-263-7860 and charge to your Visa or Mastercard.
Thanks,
Robert
