Pump 2 Does Not Work! If Pump 2 is not working in any speed, carry out the following tests to correct the problem: Pump 2 fuse
1• If Pump 2 does not work in either speed, replace Pump 2 fuse. 2• If replacing fuse does not correct problem, or if Pump 2 works in one of two speeds, read voltage on the board for both speeds.
3• Turn Pump 2 to high speed and measure voltage between white and red wire connectors: 240 VAC pump: P58 & P22 120 VAC pump: P45 & P22 The reading shoud be: ≈240 VAC for a 240 VAC pump ≈120 VAC for a 120 VAC pump 4• If voltage is correct, replace Pump 2. 5• If not, replace board.
Turn pump 2 to low speed and measure voltage between white and black wire connectors: 240 VAC pump: P58 & P35 120 VAC pump: P45 & P35 The reading shoud be: ≈240 VAC for a 240 VAC pump ≈120 VAC for a120 VAC pump
