See
RELATED PRODUCTS below for heater replacements.
Tip: Burned circuit boards or burned heater relays are often due to a loose electrical connection or a bad heater or both.
If all connections are tight and if the heater is good then the heater relays are probably old and worn out.
If a burned relay was powering a pump and all electrical connections are tight then the relay is probably old and worn out or the pump might be bad or going bad or all three.
Replacing the heater and/or pump with a new one is recommended if any of those scenarios apply.
