Possibly poor water flow. Clean all the baskets, pump too and backwash/clean the filter. If water flow is ok it might be the temperature control. If you are running it on "pool" try using the "spa" control...

If it is propane there is likely soot around the exchangers. the pentair heaters all have poor circulation and bad design. cavity is overheating the sensor

Why does my 1994 Nissan Pathfinders fuseable link keep blowing?


A fuseable link is a an "inline fuse" that works the same as a traditional fuse. When an excessive amount of current (amps) is detected, it opens to prevent fire or overheating of the wire.

It may be due to chafed insulation on the wire that when contacting body, frame or other grounded metal - causes a brief short circuit - and blows the link. Replacing it is the easy part - finding the cause can be labor intensive.

Good luck!

How do i fix my home heater, fired it up, ran for about 3-5 min. But never fired up. Replaced bad pressure switch, n heater venting tubing!


If you have a code indicating pressure switch thid is 50% of the time the barbed port on the induced draft assembly where the pressure switches tubing connects. Carbon builds up in this port requiring reaming, I use a small drill bit and insure I can feel, sense the blower wheel to insure it is clear, it is easy to be fooled as the carbon is tough at times.
If this is not it you have a bad board assuming the pressure switch is closing and opening as it should which can be determined by using an ohmmeter. or voltmeter.

Will it run without the new tubing you installed?

I have a 1995 chevy g30 that i have rep[laced disttributor , eck and full tune up still no fire or fuel any suggestions


Are you getting fuel pressure to the throttle body ?
Does the check engine light come on when you turn the key on ?
If you are not getting voltage to the fuel pump and no voltage to the coil I would check the computer to see if it is getting power then proceed in checking the fuses and relays for power. Could be something simple like the key switch or a fuseable link.

Pump starts runs for five seconds and then kicks off will not fire


If you have never checked/changed your filter or checked the pump pressure that is where your problem is. I have a tip which will guide you through the process at http://www.fixya.com/support/r4124129-yearly_maintenance_reddy_heaters Let me know if you need any more help. I would advise getting the pressure gauge they have for setting the pump pressure.

Heat works fine during the day at night it stops if you run hot water power vent turns on then boiler fires is it the presure swith in the power vent its model ck-92fal thanks ron


Turn on the boiler and jump out the pressure by putting a wire between the 2 electric connections only after the unit fires up than put the jumper on, if it runs ok it is the pressure switch.
