New Rheem Efficiency Not working

We are having intermittent problems with a new Rheem forced air gas furnace high efficiency.

We installed it about 4.5 weeks ago. It seemed to work fine for about 2 weeks or so then one morning we got up and the house was about 60 degrees and the furnace did not seem to ignite although it seem to try when you turned it off/on on the thermostat.

We found that when we turned it off and then several hours later turned it on again that it mysteriously started working. This is what we've been doing for the past couple of weeks but it is concerning as it gets colder outside.

The man who installed it came by to check it out but of course it was working and he did not see anything wrong the first time this happened.

As it increased in frequency where it is happening every night, he asked that we check the signal lights when it is not working. It said that the pressure switch is on but the amber light never comes on which means the igniter came on.

Now, he thinks the pressure switch needs to be replaced but I'm working if it is broke why is it working part of the time? And seems fine after a period of rest?

Any help would be greatly appreciated.
