Troubleshoot remote controls

Often these devices arrive and one of the modules does not work
Usually the remote control will work with at least two of the modules.
Sometimes one of the push buttons stops working.
Look if remote control has indicator light that lights up when button is pushed.
Make sure remote control has battery. Usually the battery is 12 volts.
Signal can trave through a door, but generally not through a wall or very far from remote.
Unplug module from wall and push and hold the button located on front of device
Stand directly in front of module with remote control, and push ON button
Push and hold ON button several times
Move module to different outlet
Make sure light is ON and working... then plug light into module.
Do not use for heavy motor loads... read load rating on package before installing
These devices last a few years
Return remote controls. -or- Buy another set and have back-up.

Troubleshoot digital timer modules

Open links under each image on left to find manual and wiring for each timer:
1) Reset and reprogram timer. Reset button is usually a round hole for toothpick or paper clip... but can also be a button
2) Check that load is operational. Check the light bulb is working.
3) Do not exceed load rating on timer/ check the manual for load rating and load type. Look at markings on timer.
4) Some timers are not rated for motors. Use intermediate contactor or relay. Contactors are made for heavy-amp loads Resource for contactors
5) Check that wiring terminals are not burned or corroded.
6) These small timer modules are ususally rated for 15 amp, or 12 amp safe maximum. Use fuse when drawing power from larger amp wire.
67) Timer modules are available for different voltages from 12-24 volt AC/DC, 120VAC, 208VAC, 240VAC... make sure correct voltage is connected to timer. Wrong voltage can damage timer. Look for model number and voltage on back of timer.
8) Timer must be connected to voltage to retain function and be programmed if back up is depleted.
8) Some modules have replaceable battery (PB series). Most modules have internal, non-replaceable battery that holds memories during power outage, ranging from several hours to several days.
10) Modules are frequently offered with either 24-hour or 7-day programming. If timer is 24-hour, then the display will not offer selection of day(s).
11) Each of these modules has separate terminals for connecting power. These are timer terminals, and operate the timer clock and switching relay.
12) Each of these modules has separate terminals for switching that are dry or receive no power when power is connected to timer terminals. Dry switching terminals mean you can switch other voltages besides just the voltage that is connected to run the timer.

6) Some models have power back-up. (FM1 ans MIL series have power carryover models)
7) Some models have manual override, or mode setting. FM1 and MIL series have permanant override, while spa timer override resets at next tripper.
8) Timer must be connected to voltage to function. But you can manually rotate timer dial to check if load is worling.
8) None of these modules has replaceable battery (PB series).
9) Modules are frequently offered with either 24-hour or 7-day programming.  Look at specification sheet before buying module.
10) Each of these modules has separate terminals for connecting power. These are timer terminals, and operate the timer clock and switching relay.
11) Each of these modules has separate terminals for switching that are dry or receive no power when power is connected to timer terminals. Dry switching terminals mean you can switch other voltages besides just the voltage that is connected to run the timer.

Troubleshoot box timers

Turn circuit breaker fully OFF and then fully back ON
Blow dust out of timer and add bit of WD40
Check that load is operable
Check rating plates on timer and on Load. Make sure timer is rated for the Load amps.
Check rating plate on timer for voltage. Match voltage with electric supply from breaker box.
Check rating plate on Load. Match voltage of timer with voltage of Load
Use only solid copper wire. No stranded wire.
Check that only copper wire and no insulation is under screw plate.
Look for burned contacts and loose wire
Keep box cover closed
Maximum 2 wires under screw plate. Do not put 2 different size wires under same screw plate
Only copper wire under screw plate. Cut back insulation so no insulation under screw plate.
Check wiring... if load and line wires are reversed, timer will stop after tripper passes See all box timer wiring

10 gauge or 12 gauge?

10 gauge is larger/ for 30 amp breaker. 12 gauge is smaller/ for 20 amp breaker
10 gauge wire can have black-white or black-red
12 gauge will have black and white wires

Buy short pieces 10 and 12 gauge wire at local box store
Compare with your wire.
Match color code and amp rating for wire
With 120 and 277 Volt circuits, white wire is always Neutral, and black is Hot
With 208 and 240 circuits, both wires are Hot, and both wires carry voltage
Add black tape when white wire carries voltage (applies to 208 and 240V circuits)
