Description

The Raypak 009493F is the OEM rocker switch used on Raypak gas pool heaters. It is titled for the RP2100 digital gas models R185B, R265B, R335B and R405B, and the same part is also listed as fitting the A series heaters: 130A, 206A, 207A, 266A, 267A, 336A, 337A, 406A and 407A. The source notes it may fit further Raypak models, so it is worth comparing against the switch you are taking out.

The symptom

A heater that shows nothing at the display while there is power at the terminal block and gas at the valve. The rocker switch is the last thing between the two, and it is the part most likely to have failed, because contacts that carry a load arc a little every single time they open.

What to expect

It is a small part with two connections and it drops into the same opening. The one thing worth taking seriously is the voltage: shut the heater off at the breaker before opening the panel, and if working around live wiring is not your area, hand it to a pool technician.
