SOURCE: low pressure reading on Pool Heater

I had this problem with ours last year. I replaced the water pressure switch and it began working fine. We later had a symptom that the blower would start but it would not ignite. The ignitor rod was corroded so I took it out and sanded it with some sandpaper---worked fine...until I dropped it trying to reinstall and it broke. Bought a new one and it works fine now.

Today's problem is related to the blower now.... it is always something, isn't it?!?

SOURCE: Laars Lt heater will not start- pressure switch light

it is time to check your filter make sure is not dirty and if your filter is clean and still doing this then the problem can be with one of the safety sensors they do have 2 hight limit switch located in the heater heather they re round with two wires on each one turn power off to heater and get a voltemer reader and check the hight limits for continuty they should read zero on your metter it can be your temp sensor heaters are so complicated that it is always good to have a pool tech service it I was a pool tech in california but now I am located in georgia

SOURCE: my laars lx pool heater is blinking LOW PRESSURE.

The heater needs good water flow or it will overheat. You probally have a full basket in your pump or your filter is dirty.
