Maytag Tilt Lock Spring - M...

Product details
Part B370-3800 is the tilt lock spring inside the Maytag M1200 upright, the small coil that holds tension on the recline mechanism at the base of the handle. It is the reason the handle catches and stays upright when you are done vacuuming, and the reason it drops smoothly into cleaning position instead of falling loose.
A weakened or broken spring shows itself fast. The handle stops catching in the upright position, or it tips back with almost no resistance and feels loose the instant you angle it down, or the foot pedal needs several presses before the lock finally engages. None of these symptoms are dangerous, but repeated forcing puts real strain on the plastic housing around the pivot.
This kind of failure comes from cycle count, not from any single accident. Thousands of recline motions over years of use is usually the whole explanation, and the fix sits at the base of the handle, a contained job that does not touch the motor or bag compartment. A quick way to confirm the spring rather than the pedal linkage is at fault is to watch the mechanism directly while working the tilt pedal; if the linkage moves freely but nothing pulls the handle back upright, the spring itself has lost its tension.
- Part: tilt lock spring, B370-3800
- Fits: Maytag M1200 upright
- Function: holds tension for the handle's recline and upright lock
- Symptom of failure: handle won't catch upright, or reclines with no resistance
This replacement spring is listed for the Maytag M1200 specifically, so the handle catches and reclines the same way it did when the machine was new.
