Hmmm, my pump is not variable that I know of. It's a 1.5 hp Whisperflo.

We have a two-year old pool with a MasterTemp 4000 gas heater. It had been working fine, but when we tried to heat the spa the other day the heater ignited, ran for 15 seconds then shut off. We have replaced the thermostat, a relay and the igniter, but the problem persists. Any thoughts...
