The problem is probably in your control box. Judging by the year of your coach, you probably have what is referred to as the
NEW control.
ANY ONE OR TWO JACKS WILL NOT RETRACT AT ALL;
PROBABLE CAUSE - FUSE ON CONTROL PANEL BLOWN
OLD CONTROL:
- REPLACE FUSE XF5 FOR FRONT JACK(S) ON TOUCH PAD
NEW CONTROL:
- REPLACE ‘FRONT LEGS’ FUSE ON CONTROL BOX
Your problem may not sound like it could be a fuse problem, but the mentioned fuse only comes into play on RETRACT.
On EXTEND, the specific valve must be opened and the motor/pump started. This is ONE power path.
On RETRACT, the specific valve (and the dump valve) must be opened, BUT the pump is NOT started. This is a separate power path.
Check that fuse. Good Luck
