My Pool Heater Won't Turn On
This is the call we get most often. The fan won’t come on, the burner won’t fire up, or the display is completely dark even though the breaker looks fine. Sometimes the heater kicks on for a moment and then shuts off before the water ever warms.
The most common causes we find on Plano equipment pads:
- No power reaching the unit from a tripped breaker, failed transformer, or chewed wiring
- A burner that won’t ignite from a failed igniter or gas supply problem
- A pressure switch reading low water flow from a dirty filter or a clogged pump basket
- Failed temperature sensors telling the heater the water is already warm
- A nest or debris inside the cabinet blocking airflow, which is more common in North Texas than most homeowners expect
Because low water flow mimics a dead heater, we check your pool filter and circulation before condemning any heater component. Fixing the real cause the first time is what keeps the repair quick and keeps the cost down.
It Turns On, But It Won’t Heat Up
A heater that runs but never gets the water hot is usually losing the race against flow, gas supply, or a failing internal part. Homeowners describe water that climbs partway to the set temperature and then falls back, or a spa that takes hours to feel warm.
Partial heating problems we repair in Plano include:
- Water that reaches the high nineties and then drops instead of holding temperature
- A heater that shuts off mid cycle before the pool is warm
- Heat you can feel at the unit that never seems to reach the water
- A system that overheats, runs hot, and then quits entirely
Each of these has a different root cause, from bypass valves to heat exchangers to control boards. That is why we diagnose before we quote.
It Heats the Pool But Not the Spa
The spa and pool split is one of the most common heater complaints we hear from Plano homeowners, in both directions. The heater works in spa mode but not pool mode, or the spa stays cold while the pool warms just fine.
This is usually not the heater at all. Diverter valves, actuators, and pool automation settings control where heated water actually goes. Our technicians test the full loop, from the heater through the valves to the returns, so the fix lands on the part that actually failed.
Repair or Replace? What an Honest Heater Diagnosis Looks Like
Almost every heater call ends with the same question: do I need to replace it, or can it be fixed? The honest answer is that nobody can tell you over the phone, and you should be suspicious of anyone who tries.
Our technicians are not paid on commission, so the recommendation is based on what your heater needs and nothing else. Many heaters that seem dead come back with a repair that costs a fraction of replacement. When the heat exchanger is corroded, the unit is no longer supported, or repair costs are stacking up season after season, we will tell you plainly that replacement is the better investment.
What it costs to find out: Dispatch is complimentary, so there is no fee to get a technician to your home. Diagnostics and troubleshooting that require tools or disassembly to identify the root cause are a professional billed service, and we tell you before that work begins. Our pool service pricing page explains how service costs work.
Is Your Pool Heater Running Up Your Gas Bill?
A heater that turns itself on, runs constantly, or heats the whole pool when you only wanted the spa can add hundreds of dollars to a monthly gas bill before anyone notices. Plano homeowners usually discover this problem on the bill, not at the equipment pad.
If your gas bill spiked, we look for:
- A heater cycling on by itself from a stuck relay or automation fault
- Valve settings sending heated water to the pool when only the spa should be running
- A thermostat or sensor that never registers the set temperature, so the burner never rests
- An older unit burning far more gas than a modern high-efficiency or heat pump system would
For homeowners who heat regularly, we also install and service heat pump pool heaters, which maintain comfortable temperatures through most of the North Texas season at a much lower operating cost. We install and service equipment from Pentair, Jandy, Polaris, and Hayward.
Pool Heater Error Codes We Diagnose in Plano
Modern heaters report faults through codes that range from useful to incomprehensible. An open flue sensor error, a flow or pressure code, or a board fault each points somewhere different, and replacing parts based on the code alone is how repair bills grow.
We diagnose error codes on Pentair MasterTemp, Hayward, Raypak, and Jandy heaters, confirm the underlying cause, and fix that. If your heater is flashing a code right now, note it before you call and we will know where to start.
Smoke or a Gas Smell? Turn It Off First
If your heater is smoking or you smell gas when it fires, turn it off and leave it off. In North Texas, debris and nests inside the cabinet are a real fire risk on the first cold-weather startup.
Call us before running it again. A first-fire inspection clears the burner tray, checks the gas connections, and confirms the unit is safe to operate.

Plano Pool Heater FAQs
Why won't my pool heater turn on?
The most common causes are power problems, a burner that won’t ignite, low water flow tripping the pressure switch, failed sensors, or debris inside the cabinet. Several of these produce identical symptoms, which is why we inspect the whole system before replacing anything. A dirty filter alone can make a healthy heater appear completely dead.
Why does my heater heat the pool but not the spa?
Usually the heater is fine and the problem is in the valves or automation that route heated water. A stuck diverter valve or a failed actuator will warm one body of water and leave the other cold. We test the heater, the valves, and the automation settings together to find where the heat is actually going.
Do you charge a diagnostic fee to look at my heater?
Dispatch is complimentary, so there is no fee to get a technician to your home. Comprehensive diagnostics and troubleshooting that require tools or disassembly to identify a root cause are a professional billed service, and we tell you before that work begins so there are no surprises on the invoice.
Should I repair my pool heater or replace it?
It depends on what failed. Igniters, sensors, switches, and boards are usually worth repairing. A corroded heat exchanger, a unit that is no longer supported, or repairs stacking up every season point toward replacement. Because our technicians are not paid on commission, the recommendation reflects your equipment’s condition and nothing else.
Which pool heater brands do you service in Plano?
We repair, service, and install pool heaters from Pentair, Jandy, Polaris, and Hayward, including gas heaters and heat pump systems. If you have a Pentair MasterTemp that won’t fire up or a Hayward showing a fault code, note the model and the code before you call and we will know where to start.
Why did my gas bill spike after running the pool heater?
A heater that cycles on by itself, valves sending heated water to the whole pool instead of the spa, or a sensor that never reaches its set point can burn gas around the clock. We trace the cause and fix it. For frequent heating, a heat pump system can cut the operating cost substantially.
