If pressure switch is fine then the control board is at fault and needs to be replaced.

You should have continuity at the switches. Have you checked the wiring?
Place a probe on two terminals and note the reading. Now move one of the probes to the other terminal and note the reading. Finally test the third pair and note the reading. The multitester should display a reading of infinity or continuity for each test. In this test two of the pairs should read infinity and one should read near zero resistance (continuity).
Now blow gently into the air pressure connection and retest. It should click and you must maintain the air pressure while testing. For the two pairs that read infinity one should now show good continuity. The pair that previously gave of reading of continuity should now give a reading of infinity.
If the switch fails either of these tests, it should be replaced.
Im not real sure on that at the moment as my tech site is down and I cannot access the diagrams. There should only be one pressure switch though.
Alright, just use the paperclip to attach the photos.
