Craftsman Tool FAQ: Garage Door Opener Troubleshooting, WR22SE Specs, Ratchet Wrench, Bit Holder & Dremel Bits

Before you scroll to the question you need, a quick confession: I'm the guy who replaced a perfectly good Craftsman garage door opener circuit board and then paid a mechanic to fix what I broke. Since 2011 I've documented more than 30 of those mistakes—roughly $4,700 in wasted parts and rework. This FAQ is the checklist I wish I'd had before spending that money.

Here are the Craftsman questions I hear most often, answered from experience that cost me something.

1. Why won't my Craftsman garage door opener close?

Most of the time the motor is fine. The opener opens the door but won't send it back down, so it clicks and reverses. The usual suspect is the safety sensor pair near the bottom of the tracks. Both sensors need a clear line of sight. If one gets bumped, you get the exact same symptom as a dying logic board.

Here's the causation-reversal part: people think a worn motor causes the door to reverse. Actually, the opener is doing what it was told—the sensor signal broke, so it refuses to close. I once replaced a $180 logic board because I didn't check the sensors first. A bent sensor bracket was the whole problem. A 50-cent shim and ten minutes of work, and it ran perfectly.

Check the wall control for a lock icon. If the lock feature is active, the remote can open but not close the door. That's not a dead remote, even if the LED lights up. I can't tell you how many times I've seen someone program a new remote for a problem that was just three presses of the lock button.

Then check the travel limits. If the door touches the floor and bounces back, the down-limit is too tight. Turn it a quarter turn in the direction labeled on the opener panel and test again.

This worked for me on a 2012 Craftsman 1/2 HP chain-drive. If your opener is a newer belt-drive with battery backup, the switch might be a menu in the wall console instead of a screw, but the order is the same: sensors, lock, limits, then parts. Why that order? Because it starts at $0 and only goes up from there.

2. What are the real Craftsman WR22SE impact wrench specs?

The WR22SE is an older 1/2-inch corded impact wrench. The owner's manual on my bench says:

• Drive: 1/2-inch square
• Motor: 7.5 A, 120 V AC
• No-load speed: 2,300 RPM
• Impacts per minute: 2,800
• Max reverse torque: 300 ft-lb

I'm reading those from the manual, not from memory, because my memory of the torque changed between the first time I tested it and the second time. The spec plate on the side of the tool is the source of truth.

Should you buy one used in 2025? If you need a corded workhorse and don't mind the weight, yes. It won't sit on a charger when you reach for it, and 300 ft-lb makes short work of lug nuts. If your job involves tight spaces or rusted suspension bolts, you'll want more torque or a battery-powered high-torque wrench. This is one of those context-dependent calls.

Watch out for inflated spec claims online. The FTC says advertising claims have to be truthful and substantiated (ftc.gov, accessed January 2025), but that doesn't stop someone from listing a 300 ft-lb tool as 450. If you're buying sight unseen, ask for a photo of the nameplate. If they can't provide it, keep shopping.

3. Craftsman ratchet wrench: Which type should I buy?

First, know what you're asking for. "Ratchet wrench" can mean the handle you click sockets onto, or it can mean a one-piece ratcheting box wrench. I use both. They do different jobs.

If you're building a starter set, get a 3/8-inch drive Craftsman socket ratchet and a metric ratcheting wrench set. The socket ratchet covers most work under the hood. The ratcheting wrench gets into spots where a socket won't fit, like holding a bolt head above a fuel line.

Don't get hypnotized by the tooth count. A 72-tooth ratchet is nice, but an older 36-tooth Craftsman still works if you keep it clean and don't lean on it like a cheater bar. I've got a spare 3/8-inch ratchet that I bought in 2005—actually, let me count. It was in a garage sale bin in 2006, so it's older than that. Still works.

My one real mistake was using a ratcheting wrench for final torque. I broke a gear wheel and had to walk into the parts counter with my tail between my legs. The replacement was free. The lesson? A ratcheting wrench is for spinning fasteners, not for breaking them loose.

As for drive size: 1/4-inch for small work, 3/8-inch for 90% of automotive work, 1/2-inch for suspension and larger fasteners. You probably knew that. What I didn't learn until years later is that a flex-head ratchet is a second tool, not an all-in-one. It's handy, but not mandatory.

4. Why does my Craftsman screwdriver bit holder keep dropping bits?

Start with the bit, not the holder. A 1/4-inch hex bit with a worn detent will fall out no matter how good the holder is. The holder uses a spring-loaded ball bearing to catch that little notch on the bit. If the notch is rounded, there's nothing to catch.

People think a stronger magnet will fix it. Actually, the magnet is there to hold a screw on the tip, not to retain the bit. A screwdriver bit holder can have a great magnet and still drop bits because the detent spring broke. The surprise wasn't the broken spring—it was how fast a $15 holder can fail once grease gets in the collar.

Clean the collar with compressed air and see if it snaps all the way forward. If it feels spongy, replace the holder. If it clicks but bits still slip, swap the bit.

One last thing: match bit length to holder depth. A 1-inch bit fits in a 2-inch holder, but the extra exposed shank makes it wobble. In a magnetic screwdriver, wobble means stripped screws. That's why I keep a short Craftsman bit holder on the workbench for deck screws and a longer one for reaching into the mower deck.

5. How do you put a drill bit in a Dremel?

Loosen the collet nut with the little metal wrench from the case, slide the drill bit into the collet, then tighten the nut while pressing the spindle lock. That's the whole process. If you lost the wrench, buy a replacement before you try pliers. Pliers will damage the collet and the bit will wobble.

The part people miss is that a Dremel doesn't use a standard drill chuck. It uses a collet sized to the bit shank. On a Dremel 4000, common collets are 1/32-inch, 1/16-inch, 3/32-inch, and 1/8-inch. If the bit shank is smaller than the collet, it won't center. You'll feel it immediately—the tool shakes like a paint mixer.

For the Craftsman rotary tool I own, the process is identical. Spindle lock, collet nut, one wrench. The collet size is stamped on the nut. Don't force a 1/8-inch bit into a 3/32-inch spinner. It won't fit, and you'll bend the flutes.

Use the spindle lock and keep the wrench in the case. I've lost that tiny wrench three times, and after the third time I taped it to the power cord. Not elegant, but I haven't lost it since.

6. What does Craftsman's "lifetime warranty" actually cover?

Not as much as the phrase sounds. Craftsman has historically covered hand tools—ratchets, wrenches, sockets—under a lifetime replacement policy. Power tools like the WR22SE impact wrench and garage door openers fall under a different warranty with a time limit. The printed manual for each product tells you which one you're dealing with.

I've seen guys bring a 20-year-old electric impact wrench to the parts counter expecting a free new one. That's not how it works. The coverage is whatever the warranty card said when the tool was new.

This is the same reason I ask about hidden costs before I ask about price. When someone says "lifetime warranty," I ask what's not covered. The vendor who tells you the limits up front is more trustworthy than the one who lets you assume. That's not a claim that any tool lasts forever—it's a claim about how you'll be treated if it fails.
