Pentair / Sta-Rite Max-E-Therm Topside Control Board Enclosure & Membrane Keypad Kit (NA/LP) | 77707-0013
The Pentair/Sta-Rite 77707-0013 is a replacement topside control enclosure and membrane keypad kit for select Sta-Rite Max-E-Therm (NA/LP) gas pool and spa heaters. This kit restores the sealed push-button control interface on the heater when the original membrane pad is worn, unresponsive, cracked, or water-damaged, and it replaces the outer enclosure/lid section that supports and protects the controls.
Compatible Heaters
- Sta-Rite Max-E-Therm (NA/LP series) heaters that specify 77707-0013 on the electrical system parts diagram
- Common model families: SR200, SR333, SR400 series (verify by your heater data plate and parts diagram)
What This Part Does
- Replaces the sealed membrane keypad so buttons register correctly again
- Replaces the control enclosure/lid to help protect the topside interface from weather and splash
- Helps resolve symptoms like stuck keys, no response, intermittent button operation, or a cracked/peeling keypad
What’s Included
- Topside control enclosure (cover/enclosure panel for the control area)
- Membrane keypad (button pad applied to the enclosure)
- Note: This is a control-surface/enclosure kit. The main electronic control board is typically a separate component.
Common Reasons to Replace
- Buttons are hard to press, don’t respond, or register incorrectly
- Membrane is cracked, bubbled, peeling, or has moisture intrusion
- Sun/heat damage has made the keypad brittle or unreadable
- Control cover is broken or no longer seals/fastens securely
Installation Notes
- Turn off power to the heater at the breaker before servicing.
- Take a photo of existing connections before disassembly to ensure correct reassembly.
- Inspect wiring and connectors for corrosion or heat damage while the control area is open.
- After installation, confirm all buttons function and the heater operates normally through start-up and shutdown.

Maintenance Tips
- Keep sprinkler spray and direct hose water off the control area to reduce moisture intrusion and keypad failure.
- Ensure the heater is properly bonded/grounded and protected by a functioning GFCI where required.
- If the keypad fails repeatedly, inspect for water entry paths (cover fit, missing fasteners, cracked housings) and correct the root cause.
- Maintain adequate clearance and ventilation around the heater—excess heat can shorten the life of control surfaces and plastics.
