The low pressure sensor can't be 'jumped' out on them.
The HVAC control head determines a low charge by monitoring the circuit from the pressure cycling switch. If the cycling switch will not allow the compressor to run more than 1.5 seconds, ten times in a row, the control head assumes a low charge and disables the compressor until reset.
There has been a factory service bulletin, (not a recall) for that type of concern.
Here is a link to what it states. You can copy and paste it into a new browser and rate the answer on this page.
