    When I push in my password on my keypad, I hear the click, but when I turn the knob to the unlock symbol it still doesn't open. I'm getting kind of scared, because I have actually some valuable stuff in it!

My garage furnace won't turn on the igniter and even if I heat the heat sensor manually, it won't open gas. It has the Honeywell smart valve Sv9540 in it


If the gas valve has the brown round knob, then there is a little slide-out circuit board underneath when you remove the two special security bit screws, prone for bad solder connections. The solder cracks right where the plugs attach. If it does not have the brown knob, it sounds like bad gas valve.

We have a Honeywell T8132A1049 thermostat/ cooler- we can't find a manual for it. It also says Bat Low on the screen but I have replaced the batteries with brand new ones and tried resetting it .....


Here is a link where you can download the user manual. It says to remove the batteries, wait 1 hr, then install fresh batteries. When the page for diplodocs opens click on security number and enter the code it shows to download the manual.

I live in a mobile home and I cannot light my pilot


Are you sure it has a pilot light? Some of the newer heating systems do not have a pilot light but a glow bar ignition. Lets open up the door and I need you to look for the gas valve. The gas valve will have a number of pipes attached to it and it may have two small pipes that go into the burner box. The gas valve will have a knob on it that indicates On, Pilot and Off. If you have this knob, yes you do have a pilot. Align the Pilot position with a line on the gas valve. Push in or down on the knob. Follow the two small (1/4" and 1/8" pipes into the burner box and with a long match or grill lighter, hold the flame over the pilot assembly. Once the pilot is lit, continue to hold down the knob for a minute or two. Lift up on the knob and see if the flame on the pilot stays on. If it does, turn the gas knob to the On position. If it does not stay on, there is an issue and a technician must be called.
