Look real good at the terminal block. Look at both the left side and the right side of the terminal block. O should be there! You probably do not own a heat pump. Also have patients when programing the thermostat!

Very likely whatever made the terminal block break caused the internal thermal fuse inside the dryer blow,causing the dryer to now not start.

Hi smargyle,

Welcome to fixya!

I can provide you with diagrams for the old Carrier therm and for the new Filtrete therm. But, I would need to know what the model numbers are for each therm plus how many speeds AC you have.

Please reply back with that information and we will get your AC back in working order.

Im getting harassing texts on my cell ph and would like to block the number

Blocking a number depends on the model of phone and carrier. What sort of phone do you have? Which carrier (AT&T, Sprint, Verizon, T-Mobile, etc.) are you on?

Is this a heat pump? Look in the thermostat. You should have something like the following.
Red wire to R terminal
Green wire to G terminal
Yellow wire to Y terminal
White wire to W or W1
Blue or Orange wire to the O or B terminal
Brown wire to C terminal.

Let me know what you have in the thermostat. The wire colors are not always the same.

The terminal block is always at the rear of the oven.
There should be a removeable cover, which will expose the terminal block.
It may be screwed on, or a lift up plastic cover, but it will be there.

Emerson model 8117w stop working all at once

This microwave has three door interlock switches and a fuse that are easily replaced by the consumer. Unplug the microwave. Remove the cover by unscrewing the 5 screws on the cover. Four are on the back, one on the lower right. One or more of the screws may be torx T15S (security)(bit available at hardware stores). As in all microwaves the capacitor should be discharged by shorting the cap terminals together. Note that the three switches are in a single black plastic carrier. Remove the two screws securing the carrier and the switches can be released by hand. Replace one at a time so as not to confuse the wiring which is push on spade terminals. Replace the fuse with a 20 amp 125v slow blow (radio shack). Do not plug in power until all the switches are reinstalled as a safety feature will cause the fuse to blow again. If fuse blows repeatedly it is most likely that all three interlock switches are not closing properly. Check to make sure that all switches are seated correctly in the black plastic switch carrier and that the 2 carrier screws are tight. Observe the switches as the door is closed. Replace switches and/or carrier as needed. While the cover is off you may want to clean off the fan and/or replace the bulb. Also check for proper seating of the control board connections.
