My timer is loosing approximately 3 hours a week.

if the battery is good, time ti replace timer. $20..0 home depot, the timer is not repairable.

Spray WD40?
If the timer still works, then the loose part should not be a problem.
The time-now arrow points at about the 1:30 position.
You can rotate dial until current time lines up with approximately 1:30 position.

Water Heater Timers Save Money

If you need further help, I’m available over the phone at https://www.6ya.com/expert/gene_9f0ef4df2f9897e7

Thank you for very clear question, and timer identification.
1) I don't have repair for defective timer.
http://waterheatertimer.org/Intermatic-timers-and-manuals.html#DT300
http://waterheatertimer.org/pdf/DT300-series-manual.pdf

2) Choose DT300 format
#3 says to press-and-hold CLOCK button until display shows 24H or 12H
Then release CLOCK button.
Next press HOUR button to select either 12H or 24H
This lets you choose am-pm format -or- choose military-time format where 11pm is 23

3) Set current time
Press-and-hold CLOCK button throughout whole current time setting.
Do not release CLOCK button until current time settings are finished.
Next, press HOUR button, and then MINUTE button, and then DAYS button until current hour, minute and day display.
Then release CLOCK button.
If this step does not work, then timer has gone bad.
Replace with locally available Utilitec 155671 from Lowes or Westek TE06WHB from Target

4) How to set DT300 timer program for full week of operation.
Each program requires you to set program 1 ON time and program 1 OFF time
Be careful to avoid program conflicts and overlaps so timer works as expected.

For program 1 ON time, you press PROGRAM button until 1 and ON display.
Release Program button.
Then select hour, minute and days. In this case you want all days of week, so you keep pressing DAYs button until whole week displays: Mo Tu We Th Fr Sa Su

Then you set program 1 OFF time, you press PROGRAM button again until 1 and OFF display.
Release Program button.
Then select hour, minute and days. In this case you want all days of week, so you keep pressing DAYs button until whole week displays: Mo Tu We Th Fr Sa Su

If you set ON time for all days of week, and OFF time for Tu Tuesday, then timer will not work correctly.

5) Read manual and add a comment for additional help

A mechanical timer defrost cycle is approximately 23 minutes, and it occurs at intervals of between 6 and 12 hours depending on the timer. If it does not come out of the defrost cycle on it's own, your timer can be bad. Be sure the heater actually comes on while in defrost. Also be sure the evaporator (freezer) fan is on when in the cooling cycle. If both of these occur. Replace the timer. It's important that the timer be replaced with an identicle timer.....6 hour for 6 hour, and that the 4 numbers by the electrical contacts be in the same order. In addition, if there is a loose wire from the timer motor with a slotted contact at the end, make sure you follow the instructions as to where it goes.

no and yes
the lamp warning is to alert you that a timer has expired that clocks the approximated life of the lamp in "hours of use".
it is never accurate and is dependent on whether or not it was reset the last time a lamp was replaced.
reset the lamp timer in the users "setup" menu.

the lamp has NOTHING to do with color, it only provides light.

check the connections between the TV and cable/satelite box...the red.green.blue component connector...the red one is likely loose.
if this does not correct you color problem, your optical engine has failed.
very expensive repair, not for the DIY type guy.

GE 15117 manual

You might try a new AA battery.
Some guy wrote in this week and said he bought 6 timers and all the batteries were bad except 1.

Some timers, like Woods TD1300, and others have the 12 hour or 24 hour option.
You press and hold Time button to choose 12 hour or 24 hour
But GE 15117 manual says nothing about this option.

GE 15117 timer is same timer as Woods 59403
Several folks have written in past couple weeks about the Woods 59403 timer skipping over functions.
The best I can guess is your timer is malfunctioning like the other people's timers.

Woods 59403 manual is identical to GE manual, and says nothing about 12 hour 24 hour option either

I test timers for programming and wiring difficulties.
Yesterday 3 timers arrived here, and 1 didn't work.
I took it apart and tested the electronics, and something went bad.
When these timers don't work, you get your money back or throw them away.

Your problem may be with the "defrost timer" (should be located in the fresh food compartment). Typically, refrigerators have approximately 8 hours of refrigeration cycle, then approximately 30 minutes of defrost cycle. The defrost timer controls each cycle.

Contact an appliance service company.

You haven't specified which Whirlpool model you have, so I can only give a general answer which would apply to the same fault on any device with an electronic clock.

The only fix is to have the timer circuit replaced.

It's a solid state timer and non-adjustable, but can become inaccurate if the oscillator crystal goes out of tolerance. Considering the billions of timer circuits manufactured, there are remarkably few which suffer this fault, so you've just been unlucky.

With your new timer in hand look and find a slotted screw driver head that you can turn. That is to manually advance the timer. Now put the new one in and advance it to engage the compressor and fan. Might be in the middle of defrost mode. Your unit goes through 3 defrost modes in a 24 hour period. And each mode last for 20 minutes. Once you do this I could help further if that was the case. Okay ken

Have tried checking if the Power Plug is fitting tightly in the Power socket? Could be that it is loose?
