My tankless water heater won't always light up. What's usually the problem?

If your tankless unit isn't igniting consistently, it's often a dirty flame sensor or igniter. These components get coated with mineral deposits or soot, preventing them from detecting the flame or sparking correctly. Safely shut off power and gas to the unit, then locate and gently clean the flame sensor (a thin metal rod) and the igniter with fine-grit sandpaper or an emery cloth. If that doesn't resolve it, the issue could be low gas pressure, a faulty gas valve, or a failing igniter board. Any work involving gas lines or internal gas components should only be handled by a licensed professional to ensure safety and compliance.

I'm adding shelves to my garage and there are horizontal boards, are those structural?

Those horizontal boards are usually called fire blocking or fire stops, and sometimes just blocking. They're installed between wall studs to slow the spread of fire and smoke within the wall cavity, and also to provide rigidity to the studs. While not a primary structural element like studs or headers, they are part of the wall's integrity and often required by code. Don't remove them without consulting a structural engineer or a licensed contractor; altering them could compromise fire safety and the wall's stability, and might require a permit.

My dishwasher isn't cleaning the top rack at all. The upper spray arms don't seem to be getting any water.

Usually, this means the spray arm holes are clogged with food debris, or your main filter screen at the bottom of the tub is blocked. First, remove the top spray arms and clear all the small holes with a toothpick or thin wire. Then, clean out the main filter assembly. If that doesn't restore water flow, you might have a failing circulation pump or a diverter valve issue, which typically requires a qualified appliance technician.

My washing machine hums but the drum won't spin. What should I check?

The most likely cause is a failed motor start capacitor. Unplug the washing machine first. The capacitor is usually near the motor; look for one that is bulging, leaking, or discolored. Replacing a start capacitor is a common homeowner repair. If the motor itself is seized or burned out, call an appliance repair professional.

I want to replace my smart light switch with a regular single-pole switch. Is that a simple swap?

Yes, it's often a simple swap if your smart switch was wired correctly. First, turn off the circuit breaker that controls the switch. Remove the smart switch. Look for a neutral wire, typically white, connected to the smart switch. If you have line, load, and neutral wires, connecting a standard single-pole switch is usually straightforward, following its instructions. If there is no neutral wire in the box, or if the wiring is confusing, call a licensed electrician. Adding a neutral wire, if needed, is not a homeowner task and should be done by a professional for safety and code compliance.

My new door latch plate won't fit the existing hole. Can I enlarge it myself?

First, ensure your new latch is the correct backset and faceplate size for your door. Many doors have standard 1-inch edge boreholes. If it's just the faceplate recess that's too narrow, a sharp wood chisel can carefully widen the mortise. For the bore hole, if it needs enlargement, you'll need a door lock installation kit with the correct size hole saw. This requires precision; guessing wrong can split the door, compromise security, and leave you with a larger repair bill. If you're unsure, a professional handyman or locksmith can ensure the latch fits correctly and securely.

My new roof has one piece of flashing that looks off. Should I be concerned?

Absolutely. Flashing is critical for waterproofing, especially around chimneys, vents, or valleys. A single piece looking "off" on a new roof often means it wasn't installed correctly or was damaged during placement, creating a direct path for water intrusion. You need to contact your roofing contractor immediately to have them inspect it and make any necessary corrections. This should be covered under your installation warranty, but document everything with photos.

Can I put an ethernet switch inside my electrical panel cabinet?

No. Do not put an ethernet switch inside your electrical panel cabinet. These cabinets are only for electrical distribution equipment. Adding other devices is a fire hazard and violates electrical code. You need a licensed electrician for any work inside or attached to an electrical panel.

My older oil furnace needs 24V for a new thermostat. Can I use a plug-in power supply?

No, do not use an external plug-in transformer for your furnace control board. This creates conflicting power sources or ground loops, risking damage to your control board or the thermostat. A licensed electrician can safely add a C-wire adapter or an internal transformer, properly integrated with your furnace's existing low-voltage system.

Only one faucet on my double vanity has low water pressure. The other is fine. What's the usual culprit?

Start by checking the aerator on the low-pressure faucet. It's almost always clogged with mineral buildup or debris. Unscrew it, clean it out, and reinstall. If that doesn't restore pressure, look under the sink for a kinked supply line or a partially closed shut-off valve for that specific faucet. If neither of those is the issue, the faucet's internal cartridge is likely worn and needs replacement.
