If the unit is propane or gas, the flame sensor may be bad or not in the flame long enough to "lock" the circuit on. Some units require you to hold the pilot on for 10-15 seconds to heat the sensor enough to "make" the cicuit. If in doubt, call a professional because gas and propane can be VERY dangerous.
Additionally, when was the last time the filter was cleaned?
This job is best left for a qualified pool tech who knows the codes in your state. One wrong part of the installation could get you seriously hurt.

Some pool heaters have an internal bypass valve that improves efficiency by limiting the amount of water flowing through the heat exchanger. These can stick so that water flow mostly bypasses the heat exchanger...the heater gets hot but very little heat is transferred to the pool.Other answerers have suggested the following:Your airflow over the pool is cooling the water even as it is being heatedYou may not be running the pool pump long enough. Is the heater not maintaining temp? Is the thermostat turned up? Is the filter clean? When was the last time it was back washed or cleaned?You may be using the wrong size heater for your pool and the water to heat ratio that your heater is made to work with may be out.
The amount of propane a 400,000 BTU pool heater will use depends on factors like the heater's efficiency and the temperature you desire. On average, a 400,000 BTU pool heater can consume around 4-5 gallons of propane per hour when running at full capacity.
