Often if the pressure switch is open it is because of something keeping the pressuer low rather than a problem with the switch itself. If you take a small wire and bridge the pressure switch and other components in the system. If the heater fires when one of these are bridged that is where your problem. Two wires come from your gas valve and go to the pilot and another two are the safty circut. This is where you will find the components I am talking about. A small black rubber tube covers a place in the wire just above the burners and the pressure switch are the two big trouble spots.
If the black tube is shrunk around the wire then you have had a roll out problem with your flame. If it is your Pressure switch then it could be a dirty filter or a dirty basket. Or it could be a water flow problem and you will have to make all your valves are set to have water run through heater. I hope this helps.

I have a Laars pool heater, model R0096400, and I can not get the pilot switch to push down to lite it. asked a pool service guy come to fix, he could not move it too, and told me that i need a new valve....

your pool guy may be right but before spending any hard earned cash,remove phillips head screw in middle of on/off/pilot knob and remove.make sure there is no debris under knob.squirt spray lubricant along stem wait 10 minutes and lube again.replace knob turn to pilot position work it by pushing down several may stick in down position so gently pry success rate is about 70/30 for this technique
